Newbie question
显示 更早的评论
I'm new to Matlab, and I've just finished a set of calculations which gave me a final answer. Now I want to alter one of my earlier variables, so that I can see how it affects my final answer. I've tried 'edit value' on the value of the variable in question within the workspace - that does allow me to change the variable to a different value, but none of the other variables get updated, and my final result is still the same. I know it's going to be something simple....

You may be used to Excel, where a change in the value of an input variable "cascades" throughout the spreadsheet.
In MATLAB, after changing the value of your input variable, you need to reissue your other assignments to get to a new final answer. Up-arrow will let you scroll through your command history, so you don't need to retype the calculations. If you get tired of even doing this, you'll want to capture your calculation into a file (a MATLAB script) that you can run again and again as a single MATLAB command.

There is a good five-minute primer at http://www.mathworks.com/support/2011b/matlab/7.13/demos/WritingAMATLABProgram.html
