Index in position 2 is invalid. Array indices must be positive integers or logical values.

Could someone explain what is the problem?

The problem is on the line #7

datavalues = dlmread(tline);

tline = fgets(fid);

index = str2num(tline);

datacoord = datavalues(:,index);

tline = fgets(fid);

index = str2num(tline);

datavalues_hard = datavalues(:,index);

tline = fgets(fid);

index_reg = str2num(tline);

end

Inspect what the value of 'index' is before the line 6 execution.

Try to use breakpoints to check the value of index.
