MATLAB: M file is not reading variables from the workspace

evalinlsqnonlin

Hello,
I'm having problems with my script, it doesn't want to read the variables from the workspace. I tried several things, among them evalin and it still doesn't work. I don't want to have to copy the data and physically paste it to the script, does anybody knows how to solve this problem? I keep getting the error current has not been assigned, although the variable current is in the workspace already (this variable was created by another file). How can I call current from the workspace so the m file can read the variable?
Here is a short version of my file and I'm omitting the equations as they are pretty long.
Jphotototal=current(1,:); plot(lambda,Jphotototal,'ro'); hold on L0=[0.1 0.1]; options = optimset ('Maxiter',1000,'tolfun',1e-20,'TolX',1e-20,'MaxFunEvals',1000); L=lsqnonlin('recfun',L0,0,400,options);
Thanks, Francisco

Functions have their own workspaces. Scripts on the other hand run in the base workspace where you have your data.
You could always save your workspace data into a MAT file:
save ('filename','variable Name');
and then in your function use the command:
load('filename')
Apart from this you can use the following command:
VarName = evalin('base','VarNameFromBase')
and then use VarName in your function
