Could anyone help me to solve the issue in the following code:

code:

a=[4.1288    5.2574         0    4.9757    3.0069;
        0    3.7672    4.7411    3.4989         0;
   4.7132         0    4.0136         0    4.9751]
siz = size(a)
result1=randi(3,1,5)
val_list=1:3
while ~all(ismember(val_list,result1))
    result1=randi(3,1,5)
end
idx1 = sub2ind(siz, result1, 1:siz(2))
C1 = zeros(siz)
C1(idx1) = a(idx1)
D=sum(C1,2)  

When i run the code it executes and gives me the result.

But what i actuallu need is with respect to the command line

C1(idx1) = a(idx1)

i need to have one nonzero value with respect to every row and column.

But when i run the code it gives me the result in such a way all values in any of the row or column becomes zero.

Could anyone please help me on this.

Only two hours passed between you posting this question and concluding that you don't get an answer. If your work is so time-sensitive and important that you can't wait, why don't you hire a consultant to do this?
