Error using ' (line 214) Undefined function 'ctranspose' for input arguments of type 'table'. Use the ROWS2VARS function instead.

when running my code i get a odd error: Error using ' (line 214) Undefined function 'ctranspose' for input arguments of type 'table'. Use the ROWS2VARS function instead. I don't use the ctranspose function and also don't have line 214 can someone help me. My code is below, hope someone can help me

Your variable data, being created by readtable, is a table. So are the variables like MktRF_star that you create by extracting one of the variables from that table. So is the variable F you create from those variables and so is the variable Fexmkt that you create from F.

Inside your last loop you have this line of code (commented out so I can execute a line of code later in this answer.)

% model.Fbarexmkt{j} = (IdentityMatrix(model.SelMatrixF{j},:)*Fexmkt')';

Not only does that try to transpose the table Fexmkt (which won't work) but it also tries to multiply something by that table (which also wouldn't work.)

If you want to access the data inside a table array, you can use curly braces.
