I have a matrix variable, corr_matrix. I would like to save this to the workspace without having to validate (export2wsdlg requests permission before exporting). Can you do this with evalin? I did not understand evalin's documentation...but I would like something like

Save2ws('variable_name', variable);

How can this be done?

What you are asking for with Save2ws is a way to poof a variable. In general this is bad practice. Can you give some details about how/where corr_matrix is being created?

在 MATLAB Online 中打开

in my script file: inputVT()

in my function file named inputVT.m

I have

v0 = input('velocity');

this works but my input is not stored to the workspace. How do I store it to ws?

In your script,

v0 = inptuVT();

and your inputVT.m would be

function v0 = inputVT
  v0 = input('velocity');

If you would like to do this for debugging purposes, you can click on the down-arrow below "Run" and choose "Pause on Errors". This will allow you to browse the internal variables and workspace in a function in debug-mode when an error occurs.

@Matt while I try and avoid globals, I would never trade a global for a evalin/assignin. At least globals give you a fighting chance of figuring out what is happening.
