Could anybody help me with this please? I have written a function in a m file. I'd like to write another function containing only data required for calculations. I am hoping the first function can take in the data written in the second function, and calculate automatically. Rather than I have to copy and paste the data to the command panel and run the function. If i want to make any change, I can simply change the data in the second function. and run it again. Thank you very much.

在 MATLAB Online 中打开

Write two functions:

function data=Fcn1
data=[1 3 2];
function result=ProcessData(MyData)
result=MyData+1;

In Command Window, you can do:

out=ProcessData(Fcn1)

I see what you mean,however, I have tried similar methods, it is apparently not working. I have always got error as ??? Input argument "S1" is undefined. as I have a list of data in the function,e.g. s1=2,ss1=[2 3 4 5],s2=3,ss2=[4 2 6 8] and so on.
