For loop question of Iteration

Hi All,

I want to say Hi first of all as this is my first ever post.

I am working on Matlab code which utilities a lot of "For" loops and iterations. Part of the code looks like this:

for k = 1:length(TSR_vals);
  TSR(k) = TSR_vals(k);
  ....
  ....
  ....
end

My question is, what does TSR(k) = TSR_vals(k); represent? why is the k in brackets?

Thanks, Kacper

From what I could read is that TSR will refer to element 'k' as it traverses in order in the matrix for each iteration, correct?

I don't understand what you mean.

You could use the debugger and look at the values of the variables during each iteration. It could help you understand.

Set a breakpoint in the editor and use the debugger to step through and see...

Just one word of caution, however--*NB* the definition of length in the help for it -- it returns max(size(X)) for variable X. IF there are two dimensions in the array and the number of columns is larger than the number of rows, then the returned length will be the number of columns, not rows. Be sure you know which it is that you want, specifically.

Hello, KACPER PAWLOWSKI. You can see the values in each iteration. After each iteration, you must press enter to continue to next value of k. At the end, the intire TSR will be print.

for k = 1:length(TSR_vals);
    k
    TSR_vals(k)
    TSR(k) = TSR_vals(k)
    pause();
end
TSR

The way to go about this is to use the debugger. Say you wanted to perform an operation during debugging. That ain't gonna work if you do this.

You can resume execution by pressing any key, not just enter.
