MATRIXMOD (a,b,ConsiderUnits)

Description

This function gives the remainder of the number after dividing each entries of two matrices.
In $MATRIXMOD(a,b)$ , $a$ and $b$ are two matrices.
Normally we could not do the matrix division directly.Instead of that we can multiply by an inverse.
This function is taking corresponding entries and doing the division for each element.
When we divide two integers we will get the result as :X/Y=Q with remainder R.
Here X is the dividend, Y is the divisor, Q is the Quotient and R is the remainder.
So MOD(n,d)=R.So here each entries in the first matrix is divided by the second matrix and it is displaying only the remainder value.
Also the dimension of the both matrices should be the same.
Suppose the entries either row or column are more in the first matrix compared with the second matrix then those extra entries will display as NaN.
Suppose the entries are more in the second matrix compared with the first matrix then those extra entries will be ignored.
