I'm used to working in Matlab using its full GUI environment. Due to license issues I went and installed Octave, but it appears that it doesn't have a GUI, at least not one that's installed by default.
I transferred the variables from Matlab to Octave by saveing them in Matlab and loading them in Octave. Thing is, I don't remember the names because I got used to seeing them in the little workspace window which I no longer have.
How can I see the list of defined variables and their types in Octave?
The command whos will do just that.
You can use a GUI similar to Matlab, such as QtOctave or GUIOctave.
With the command whos you can even see the variables that the file has WITHOUT opening the file, to be assure that this file is the one.
For example, the name of the file is MyVariables.mat
use:
whos('-file','MyVariables.mat')
