Linear Algebra tutorial: Matrix Subtraction (original) (raw)
When we have two matrices,
and
then the matrix subtraction or matrix difference 
is a matrix whose entry is formed by subtracting the corresponding entry of
from each entry of
, that is
.
Matrix subtraction works only when the two matrices have the same size and the result is also the same size as the input matrices.
The interactive program below shows you the result of matrix subtraction. Your input must be two matrices of the same size (one matrix for each text box). Random Example will generate random matrices of the same size.
