I have created gui (using Guide) but I faced a problem. My gui has 2 buttons at the moment - one for opening the file and reading in variables, second for making a plot. Each of the buttons reffers to separate .m file. Opening button runs .m file with the script that opens the file and reads the data to the workspace, whereas the second button (that is activated after the first button was used) refers to another .m file with plots (grapf and nmerical data in the table). The opening button seems to works, but by pressing second button I get error message. I looks like it does not see the variables that should be ploted. I know that gui is using different workspace than 'base' workspace, but I thought that untill I am within the same gui I am also within the same workspace so that the varialbes that should be used for ploting are easly accessible. Apparenly it is not the case (?). My question is, how to address to the workspace which stores the demanded variables?
Unrecognized function or variable 'freq'.
