MATLAB: Is nothing being stored in the “Workspace” after I run the code

workspace

I have a video processing code, its an ALPR program I am working on. But every time I run the code, none of the usual stuff that is stored in the Workspace of Matlab is getting stored. What could be the cause of this?

You're running a function instead of a script. The variables in the function are local and vanish once you exit the function. If you want to see what their values are, set a breakpoint on the last line of your function, just before it exits.

MATLAB: Strtok return nothing

There's no 0.5 delimiter on the string, strtok should return T=5.5 but it doesn't, that's weird because it says on the documentation: If no delimiters are found in the body of the input string, then the entire string (excluding any leading delimiting characters) is returned in token, and remain is an empty string ('')

Like this [T,D]=strtok(num2str(5.5),0.5) it works like it says on the documentation.

MATLAB: Function failed to call the variable from workspace.

The variable might not be in the same workspace. If you defined it at the command prompt then it would be in the "base" workspace rather than in the function's workspace. You can retrieve variables from the base workspace:

   evalin('base', 'kinect_image')

but almost always a better way is to pass the variable to the function.
