# MATLAB: Making a matrix of same size from different matrices of same size

MATLABmatrix from matrices

Hey all,
I have tried to find solution to my problem on MATLAB community, but I couldn't. So I am here to get the soultion to my problem.
I have a three matrices of same size. Now I need to make one matrix from three different matrices of same size.
For an example;
``A = [ 0        13.2011           0             0         0;    13.2011         0          11.1861          0         0;    0        11.1861          0               0        0;    0           0              0              0       0;    0         0            0                0      0];B = [  0            0            0        0         0.0025;    0           .0256             0      0         0.0028;    .4563            0           0        0         0.0025;    0            0             0       0          0;    0.0025       0.0028       0.0025     0          0];C  = [0     0      0         0.145        0;    0    0      0         0        0;    0    0      0         18.254    0;    0    0       18.254    0         0;    0    0      0          0        0];``
Now I need D matrix of same size. It is just a simple matrix, so elements of the indices will be changed from 0 to value or value to 0 depending on the condition, so I need general solution to make one Single matrix
Note; if the element of a matrix A is not a zero, then element of other two matrices will be zero always, even for 10*10 matrix.
For an example A(1,2) = some value, B(1,2) and C (1,2) will be zero.
I tried using below solution; But didn't work.
``D (:,:,1) = - A;D (:,:,2) = - B;D (:,:,3) = - C;``
After I got the matrix D, again I have to do some calculation on D and using D. So I need D matrix as D(n,m) not D(n,m,p);
It would be fine, if the matrix D(:,:,p) become D (:,:), but contains all the elements of A, B and C, not just oly C or B or A.
I hope my question is correct.
Any suggestions and answers are much appreciated.
