how to update a variable in a .mat file for matlab?
I have a matlab .mat file that stores a bunch of variables. How do I update a single variable?
I tried doing this:
load('filename.mat');
variable='Test';
save('filename.mat',variable);
but it says
??? Error using ==> save
Variable 'C:\' not found.
What does this mean and how can I fix it?
Thank you!
Answer
I think you are looking for the "-append" option:
save('filename.mat','-append');
From http://www.mathworks.com/help/techdoc/ref/save.html
For MAT-files, -append adds new variables to the file or replaces the saved values of existing variables with values in the workspace.
