# isFloat64MatrixLike
> Test if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object containing double-precision floating-point numbers.
## Usage
```javascript
var isFloat64MatrixLike = require( '@stdlib/assert/is-float64matrix-like' );
```
#### isFloat64MatrixLike( value )
Tests if a value is a 2-dimensional [ndarray][@stdlib/ndarray/ctor]-like object whose underlying data type is `float64`.
```javascript
var Float64Array = require( '@stdlib/array/float64' );
var ndarray = require( '@stdlib/ndarray/ctor' );
var arr = ndarray( 'float64', new Float64Array( [ 0, 0, 0, 0 ] ), [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isFloat64MatrixLike( arr );
// returns true
```
## Examples
```javascript
var ndarray = require( '@stdlib/ndarray/ctor' );
var Float64Array = require( '@stdlib/array/float64' );
var isFloat64MatrixLike = require( '@stdlib/assert/is-float64matrix-like' );
var buffer = new Float64Array( [ 0, 0, 0, 0 ] );
var arr = ndarray( 'float64', buffer, [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var out = isFloat64MatrixLike( arr );
// returns true
out = isFloat64MatrixLike( [ 1, 2, 3, 4 ] );
// returns false
out = isFloat64MatrixLike( {} );
// returns false
out = isFloat64MatrixLike( null );
// returns false
```
