+# isComplex64MatrixLike
+
+> Test if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object containing single-precision complex floating-point numbers.

+
+## Usage
+
+```javascript
+var isComplex64MatrixLike = require( '@stdlib/assert/is-complex64matrix-like' );
+```
+
+#### isComplex64MatrixLike( value )
+
+Tests if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object whose underlying data type is `complex64`.
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var ndarray = require( '@stdlib/ndarray/ctor' );
+
+var arr = ndarray( 'complex64', new Complex64Array( [ 0, 0, 0, 0, 0, 0, 0, 0 ] ), [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
+
+var bool = isComplex64MatrixLike( arr );
