Please show us the exact output of these commands:

 size(tstval)
 size(stval)

[Ganesh Hegade]

check size of tstval and stval

[vasantha malairamar]

tnk u

[vasantha malairamar]

we fit the first in Stile into the first in Starget, fit the second in Stile into the second in Starget , and so on.

@vasantha malairamar: And this can work only, if both variables have the same number of elements. But they don't. We cannot guess why and what you want to do instead. But you can explain this.

The error message is clear: In the expression tstval ./ stval both variables must have the same size or one is a scalar. You can examine this with the debugger. Type this in the command window:

dbstop if error

Now run your code again until Matlab stops. Now check the sizes of the variables either in the workspace browser or in the command window:

size tstval
size stval
