What does operands could not be broadcast together with shapes?

This kind of error occur when the two array does not have the same shape. to correct this you need reshape one array to match the other.

How do you subtract two matrices in NumPy?

Subtracting two matrices in NumPy is a pretty common task to perform. The most straightforward way to subtract two matrices in NumPy is by using the - operator, which is the simplification of the np. subtract() method - NumPy specific method designed for subtracting arrays and other array-like objects such as matrices.

Is broadcasting feasible between two arrays whose shapes are?

The Rules of Broadcasting

In general, you can do arithmetic operations between two arrays of different shapes, if: The size of each dimension is the same, or. The size of one of the dimensions is one.

What is the shape of the broadcasting array resulted?

The shape of the resulting array is (4,4) because broadcasting occurs in both dimensions. The broadcasting also occurs when doing arithmetic operations with more than two arrays. Same rules apply here too. The sizes in each dimension must be equal or 1.
