Let A be a matrix A = rand(4) For all values of A >=0.5, A = 1 else A = 0
now I want to generate a new matrix Alpha..... for which all values of A which are 1 they should have value 0 in Alpha matrix and for all zero values of matrix A the Alpha should have value "pi"
Let A = [1,0;0,0] Alpha should be [0,pi;pi,pi]
Thanks for helpers....... hope i made you understand what i want.... Regards

A = [1,0;0,0] ;
iwant = A ;
iwant(A==1) = 0 ;
iwant(A==0) = pi ;
A = rand(4) ;
iwant = A ;
iwant(A>=0.5) = 1 ;
iwant(A<0.5) = 0 ;
