how can I use a name of an external variable in a function?

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...
