Hello. I'n very novice in MATLAB, so please undersatand me..!
My queation is as title.
Let me an example.
x = [1,0,0,1] % binary
A = [-27, -10, -11, -25]
In this example, first and fourth number of x is 1.
Along x, first and fourth number of A is -27, -25.
And I want to change the bigger number of this two number to zero.
Namely, -27 < -25, so -25 transfer to 0.
The result is
A = [-27, -10, -11, 0]
if
x = [1,1,0,0] % binary
A = [-27, -10, -11, -25]
the result is
A = [-27, 0, -11, -25]
How can I code this logic??
Many masters in the world, please Help me.

x = [1,0,0,1] % binary
A = [-27, -10, -11, -25]
xidx = find(x==1);
[~, maxidx] = max(A(xidx));
A(xidx(maxidx)) = 0;

x = [1,1,0,0]; % binary
A = [-27, -10, -11, -25];
idx = find(x);
[~, i0] = max(A(idx));
A(idx(i0)) = 0;
A
% A = [-27, 0, -11, -25]
