Adding parameter to file name string when saving a figure as a jpeg

43 次查看(过去 30 天)
I'm running code on different point clouds (each with their own name) to produce graphs, and the name of the point cloud is an input parameter in my function. I want the graph produce to be switched from a fig to a jpg and for the name of the file to include the point cloud name. Currently the code is running and saving as a jpg and overwriting the current jpg each time (meaning i have to go in and change the filename before running the code again). I have set the file name to be a string with the variable included to then save the figure as a jpg, but this doesn't seem to work. I've also used saveas(plt, sprintf(''),''jpg) where plt is what ive set my plot to, and this doesnt work either.
Cheers!

filename = ['Point cloud ' num2str(5) '.jpg'];
saveas(1,filename)

Iain gave an example of building/concatenating the filename string first then using it in the saveas. Since your parameters are probably numbers Iain is converting the number of a said parameter to a string such that there would be no type mismatch.
So if you look at the function help (ie type in help num2str) you'll see what it does.
