Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 1-by-2

Xindex = zeros(217,2);

Xval = zeros(201,1,217);

for index = 1:217

Xval(:,1,index) = A(:,3,index);

for rowidx = 1:201

if(Xval(rowidx,1,index)>7.227 && Xval(rowidx,1,index)<7.2510)

r = 1;

c = 1;

Xindex(r, c) = [index rowidx];

r = r + 1;

c = c + 1;

end

end

end

The underlined code is causing the error. I am not sure what is wrong as Xindex has 217 rows and 2 columns, I am trying to fit two values alongside each other in the same row. Why is a size mismatch occuring?

Please help, thanks in advance!

Does this do what you want:

Xindex(r, :) = [index rowidx];

You can get rid of c altogether since it isn't needed. And you need to move the r = 1 line to up above the start of the for loops.

Amazing, this works perfectly as intended. Thank you!
