General Matlab question

[pppbigppp]

Hi,

I'm curious if there is a way to save(export) a figure as a jpg file using only the commandline. In other word, I want to embedded the graph production in a m-script so that I don't have to click through several menus.

Also, I'm wondering if there is a way to access an array element of an output directly. Let say I have type

size(matrix)

and the return value is [1 2 3]. Is there a direct way to access the first element(1)? Currently, I have to assign the output to a, then call a(1). Would be nice to eliminate this temp variable.


Thanks!

you can use "saveas" command in matlab.

for example if you want to save an x-y plot,

h=plot(x,y);
saveas(h,'filename.jpg');
