could anyone help me to solve the issue.

i am having two different array

A =   [  0           2.9985    2.5625      0.7236;
         0              0      1.0235      3.0086;
         0              0            0     2.8162;
         0              0            0          0]
 B =[    2.9985    2.5625    3.0086    2.8162]

I want to display the A array in a way such that number present in B array should be present in A array and the rest of the numbers should be as zero.

the desired output is

                                      A=[0           2.9985      2.5625       0;
                                         0              0           0    3.0086;
                                         0              0           0    2.8162;
                                         0              0           0         0]

Could anyone please help me on this.

A(~ismember(A,B)) = 0;

But since you are using floating point numbers, I highly recommend you use ismembertol() instead of ismember()
