Hi,
with the following function:
function savefigure(data)
imagesc(data)
saveas(1,['nameofthevariabledata.png']);
I would like to the image under the name of the variable. In an example: I have a matrix "we13", so I call the function with
savefigure(we13)
and I hopefully the function saves the figure as "we13.png". I don't know how to give the name of the variable (in this case "we13") to the function, so I can use it in the function. I hope someone has an idea. Thaks a lot Jim

Do you mean something like this:
function [] = savefigure( data, filename )
imagesc(data)
saveas(1, filename, 'png');
return
Then to call the function:
filename = 'we13';
savefigure(data, filename);
Edit:
If you actually want to use the name of the source variable, then the previous answer is on the right track:
function [] = savefigure( data, filename )
imagesc(data)
saveas(1, inputname(2), 'png');
return

Thanks a lot. "Inputname" was the one I was looking for...
