Identity Matrix are the square matrix where the all the principal diagonal elements equal to 1 and other elements are zeros. Click here to get the definition of identity matrix, properties and examples.
In order to multiply two matrices A· B = C, the number of columns in A must equal the number of rows in B. This is necessary, so when computing the dot product, the vector lengths will be equal. If A is an [N × M] matrix, then B must be an [M × P] matrix to perform...
