# NumPy zeros() function

In this tutorial, we will cover `numpy.matlib.zeros()` function of the Numpy library.

The function `numpy.matlib.zeros()` is used to return the matrix of given shape and type. This method filled the matrix with zeros.

The `numpy.matlib` is a matrix library used to configure matrices instead of ndarray objects.

### Syntax of `matlib.zeros()`:

The required syntax to use this function is as follows:

``numpy.matlib.zeros(shape,dtype,order)  ``

Parameters:

Let us now cover the parameters used with this function:

• shape
This parameter is in the form of a tuple that is used to define the shape of the matrix.

• dtype
This parameter is used to indicate the data type of the matrix. The default value of this parameter is `float`. This is an optional parameter.

• order
This is an optional parameter that is used to indicate the insertion order of the matrix. It mainly indicates whether to store the result in C- or Fortran-contiguous order, The default value is 'C'.

Returned Values:

This function mainly returns the zero matrix of a given shape, dtype, and order.

Now it's time to cover a few examples of this function.

## Example 1:

Given below is a basic example for the understanding of this function:

``````import numpy as np
import numpy.matlib

print("The matrix is:\n",numpy.matlib.zeros((4,3)))    ``````

The matrix is:
[[0. 0. 0.]
[0. 0. 0.]
[0. 0. 0.]
[0. 0. 0.]]

## Example 2:

Now we will also use type and order parameter in the code snippet given below:

``````import numpy as np
import numpy.matlib

print("The 3x4 matrix with all elements in integer is as follows:\n",numpy.matlib.zeros((3,4), int, 'C'))    ``````

The 3x4 matrix with all elements in integer is as follows:
[[0 0 0 0]
[0 0 0 0]
[0 0 0 0]]

## Example 3:

It is important to note that If the `shape` has length one i.e. `(N,)`, or is a scalar `N`, then in the output, there will be a single row matrix of shape `(1,N)`. The code snippet for the understanding of this statement is as follows:

``````import numpy as np

np.matlib.zeros(4)``````

matrix([[0., 0., 0., 0.]])

## Summary

In this tutorial we learned about `numpy.zeros()` mathematical function in the Numpy library. We also covered its syntax, parameters as well as the value returned by this function along with a few code examples.
