Various changes; see description

• Added Za function: convert numbers from base to base
• Improved U (str2num) to allow conversion to more general literals
• Improved two-input version of ! (permute). Second input can now be a scalar
• Changed the order of second and third optional inputs of o (convert to double precision

array). Padding is not on the left by default

• Yo applied to strings or cell arrays changes case
• Z" (blanks) now accepts vector input
• Bug corrected in parser: space was not recognized as separator in colon literals
• Z# (fwrite) now converts the file name to char if needed, and deletes file "inout" at the

beginning of the program

• Octave compatibility: max and min now allow first and second input to be char
• Comma can no longer be used as a separator. Use space or newline instead
• Function Y} (cell2mat) has been unified with g (logical)
• Yf (prime factors) now returns an empty array for input 1
• Xd (diag / spdiags) now has one input by default
• Xd with several inputs or outputs (spdiags) now allows char inputs
• YG when used as imwrite now adds extension '.png' to filename if it contains no extension

Various changes

• Yk (closest value) now includes a third output with indices of selected values
• Z^ (Cartesian power) now allows inputs in reverse order if the second is an array of at least two elements
• m (ismember) and u (unique) now accept numeric content in cell array input
• Z+ (2D convolution; see also Y+) now produces output the same size as the input
• Bug corrected in e (reshape) for logical input
• Modular indexing has been added, only for scalar indices (thanks to @dennis for the suggestion)
• Bug corrected in ZA. In addition, now it allows cell array input, and ignores non-recognized digits
• o with cell input now allows specifying fill value and padding side
• Z} (split array) now by default splits along the first non-singleton dimension
• Added W function: 2 raised to input, element-wise
• Updated the Fibonacci example in the documentation (1 byte fewer using y), and included the new features
• YS (circshift) now allows second input to be a vector with third input specifying dimension when first input is a 2D array
• Xd (diag) now includes spdiags functionality
• format function has been integrated with ZG
• h (horizontal concatenation) and v (vertical concatenation) now linearize their inputs if sizes don't match

Quite a few changes

• bitand, bitor and bitand now allow both inputs to be char arrays. bitxor doesn't have bitcmp functionality anymore (it may be added in the future as a separate function)
• e (reshape) now has two inputs by default, and in that case adds a final implicit [] input. For size specification not matching input size it pads with values depending on input type or trims input
• Added function X@ to push current index of "for" loop
• XB now automatically converts input to logical; and works for cell array input (like ZB)
• Added function Yk: gives closest value in second input to each value in first input
• Yb (strsplit) and Zc now include a numeric-input mode
• XO (datestr) and ZO (datevec) now take two inputs by default
• Improved two-array mode of S (sort)
• Former first input of ZG (control appearance of graphics) is now the last input
• S (sort) now works on cell arrays of numeric arrays
• c (char) with cell array input now allows no-char cell contents. They automatically converted to char
• o (double) with cell array input now works in an analogous way to char: converts cell contents to double, pads with zeros if needed and concatenates vertically
• v (vertical concatenation) now takes as inputs all stack contents, by default

Various changes; see description

• Corrected bugs in set functions that produced column result when it should be a row
• Corrected bug in "next prime" function (no output was produced for certain inputs)
• cumsum and cumprod now allow maximum and minimum values
• Extended XE (replace) function for cell arrays
• Added XM (mode) function
• Added distance functions to pdist2 in Octave
• Modified the behaviour of Xn (nchoosek). Added XN (nchoosek forcing first input to be interpreted as an array)

Various changes (see description)

• Added predefined literal ' ':'~'
• Improved compatibility of Octave's disp function with that of Matlab: empty arrays now produce no displayed output at all
• Extended Octave's str2func function so it works as Matlab's. This is needed for XQ (accumarray function), so that it properly works on Octave
• Octave compatibility: chars can now be converted to logical
• prod functions can now take char input
• padarray now allows char and logical inputs
• Bug corrected in Xn (nchoosek) when first input is an array and second is 1
• YC (im2col) now allows char input in Octave. Also, in Octave it gives empty output (like Matlab, and instead of an error) if block size is too large
• Fixed trailing decimals equal to zero that are sometimes produced by Octave with symbolic output
• Ya (padarray) now allows the first input to be char in Matlab (as in Octave)
• New function E that multiplies by 2
• YS (circshift) now applies the shift along the first non-singleton dimension by default
• The three-input version of YS didn't work in Octave. Now it does

13.0.0: Various changes; see description

• Added function X#, which displays the current stack contents, for debugging
• Added function XE, which replaces elements in a numeric or char array
• Changes in initial contents of clipboard L
• Updated documentation with 2-output mode of ), Y) and Z).
• Removed unwanted whitespace from symbolic output in Octave
• dec2bin and dec2base now allow char input in Octave
• floor and ceil have been integrated with lower and upper
• Y$ (vpa) now has two inputs by default
• padarray function added

• Added predefined literals
• Expanded funcionality of ) Y) Z) to split arrays
