Solution
a=rand(3) //to create random matrix of range 0 to 1 and of size 3x3
a=a*4 //for range;
a=a+7
a=round(a) // to convert elements into int.
b=eye(3) // to create identity matrix
addi=a+b // addition
sub=a-b //subtraction
mul1=a*b //multiplication
mul2=a.*b //corresponding elements multiplication
Output :
//for a=rand(3)
