storing data from function
显示 更早的评论
Hi,
I have this code in my function file: [sound, freq] = wavread(file) and for some reason sound and freq are not being stored in the workspace. What am I doing wrong?

If you're using wavread inside a function then you have to return them to your base workspace explicitly because the workspace of a function is kept separate.
Example, will not return sound and freq to the base workspace:
function foo(file)
[sound, freq] = wavread(file)
end
You have to declare the outputs explicitly:
function [sound, freq] = foo(file)
[sound, freq] = wavread(file)
end
and call it as
[out1,out2] = foo(file)

So, you have:
function something
[sound, freq] = wavread(file);
end
? If so, you need to output those values like
function [sound, freq] = something
then when you call the function, it will spit out those values. Otherwise, they only exist in the temporary workspace of the function, which gets cleared out when it's done
