Operation on Matrices
Equality of matrices Two matrices A = [ aij ] and B = [ bij ] are said to be equal if
o o they are of the same order each element of A is equal to the corresponding element of B , that is aij = bij for all i & j .
Numerical : Find the values of x , y and z from the following equations
Soluton : Comparing two matrices we get x = 1 , y = 4 & z = 3
