Passing variables in string under for loop.

Hello,

I am trying to run the below code. Here I am passing the string with i and j as variable but it is not taking i and j as variable and showing errors.

Can some please help by saying how to do indexing with in a string and pass the values of i and j in the string in for loop as variable.

for j = 1:12

for i = 1:12

lt.Cmd('AddPickup "SPLINEPATCH_LENS_SURFACE[LensRearSurface].ZValueAt[i][j]"')

end

end

Thank you so much for reading my querry.

Regards

You need to convert the numeric values in the loops into strings. Here is how to construct the string to pass into lt.Cmd:

i = 1; % Using just a couple specific values, instead of the whole loop, just to illustrate one case
j = 2;
strcat('AddPickup "SPLINEPATCH_LENS_SURFACE[LensRearSurface].ZValueAt[',num2str(i),'][',num2str(j),']"') % You would pass this string into lt.Cmd

ans = 'AddPickup "SPLINEPATCH_LENS_SURFACE[LensRearSurface].ZValueAt[1][2]"'

The idea here is that I am creating strings out of i and j, and then concatenating all of the strings together into the one long string you need.
