Hai
I need to replace the element of matrix 'A' by matrix 'a' if the value of the element is greater than 50 and by matrix 'b' if the value is less than 50,so that i will get a 32x32 matrix.I have given the code below.Help me please.thanks
A = randi (100 , 16 , 16) ;
a=[5 5;5 5];
b=[20 20;20 20 ];
for i = 1:16
for j = 1:16
if A (i , j ) > 50
R( i,j ) = [a] ;
else
R( i,j ) = [b] ;
end
end
end

solution :
A = randi (100 , 16 , 16) ;
s=A>50;
a=[5 5;5 5];
b=[20 20;20 20 ];
R=num2cell(A);
R(s)={a};
R(not(s))={b};
R=cell2mat(R)
