It is easy to pick an odd one out! But when it comes to picking the smallest one out, especially when there is an abundance of data from which the picking is to be done, there comes the hassle! To relieve us of this burden of effort & time that a human mind shall take to do it, we find solace in the computational capabilities of programming languages.

In this article, we will look into the sequence of steps involved in finding the minimum out of the given elements in an array using the *minimum( ) *function from the *numpy *library in Python. Let us get started with understanding its syntax.

**Syntax of ***minimum( )* function

*minimum( )*function

Following are the basic constructs comprising both mandatory and optional elements that ought to be put together for the effective functioning of the *minimum( ) *function from the *numpy *library.

```
numpy.minimum(x1, x2, out=None, *, where=True, dtype=None)
```

where,

**Using ***minimum( ) *on One Dimensional Arrays

*minimum( )*on One Dimensional Arrays

Let us kick things off by importing the *numpy *library within Python by using the following code.

```
import numpy as np
```

Following would be the one-dimensional arrays for which the minimum elements within are to be determined.

```
ar1 = np.array([[1.2, 3.4, 6.7, 8.9]], dtype = int)
ar2 = np.array([[2.1, 4.3, 5.7, 6.9]], dtype = int)
```

It could be noticed above that the data type being considered is *int *so one can very well expect the output to be stripped off the decimal numbers. Now it is time to use the *minimum( ) *function!

```
np.minimum(ar1, ar2, dtype = int)
```

**Using Numpy ***minimum( ) *on N-Dimensional Arrays

*minimum( )*on N-Dimensional Arrays

Let us now extend our ask by using arrays of multiple dimensions such as those given below to return their minimum elements using the *minimum( ) *function.

```
ar1 = np.array([[1.2, 3.4, 6.7, 8.9],
[9.8, 7.6, 5.4, 3.2]], dtype = float)
ar2 = np.array([[2.1, 4.3, 5.7, 6.9],
[9.7, 8.6, 4.5, 1.2]], dtype = float)
np.minimum(ar1, ar2, dtype = float)
```

Similar to the output array of the previous section, here too each position of the output array which is of the same dimensions as the input arrays are replaced with the minimum of the values.

**Using ***where *in *Minimum( ) *function

*where*in

*Minimum( )*function

One can also selectively find the minimum of the given array elements confined to only a particular position within the array by exercising the *where *option in the *minimum( ) *function as demonstrated below.

```
ar1 = np.array([[1.2, 3.4, 6.7, 8.9],
[9.8, 7.6, 5.4, 3.2]], dtype = float)
ar2 = np.array([[2.1, 4.3, 5.7, 6.9],
[9.7, 8.6, 4.5, 1.2]], dtype = float)
np.minimum(ar1, ar2, where = [False, True, True, True])
```

The above code restricts the *minimum( ) *function to only return the minimum values of the input arrays compared in all the positions except for the first.

**Conclusion**
