How to Use imported Workspace Data in MATLAB script

Hello,

I have imported from Excel 4 Matrix coeffients (TA_11, TA_12, TA_21, TA_22 all complex doubles) which exist in the workspace, but are not defined as variables or functions in the script where I want to use them.

Now I want to define a Matrix (2x2) called TA = [TA_11 TA_12; TA_21 TA_22], in order to calculate with this Matrix, i.e. multiplication with other matrices.

This is the error message:

Unrecognized function or variable 'TA_11'.

Error in Script (line 66)

TA = [TA_11 TA_12; TA_21 TA_22];

What is to do here?

Thank you very much.

In Command Window, what do you see when you run "whos" or "workspace"?

You need to refer to them using their variable name. This is the name used in the Workspace. It was set (intentionally or not) when you imported the data.
