Write a function called mystaff that takes one input matrix called S. S is an n-by-m matrix whose elements are salaries. Salaries.xlsx Doesn't return a value How do I use my function to find average salary of principe: principle >= 140000.

Here's what I have so far
filename = 'Salaries.xlsx';
S = xlsread('Salaries.xlsx')
function mystaff(S)
if nargin~=1
error('This program takes one input matrix argument')
end
if ~isscalar(S)
error('S must be scalar')
end
pmat = S >= 140000;
p = S(pmat)
meanp = mean(p)
end

Try this:
function ArmStrong(S)
if nargin~=1
error('This program takes one input matrix argument')
end
if isscalar(S)
error('S must be a vector')
end
pmat = S >= 140000;
p = S(pmat)
meanp = mean(p)
end

Khalid,
I suspect you are pressing the "Run" button with your function file open.
Your function needs to return the final value as an output argument. So first off, change the function file to this and save it as a separate file named mystaff.m:
function meanp = mystaff(S)
if nargin~=1
error('This program takes one input matrix argument')
end
if ~isscalar(S)
error('S must be scalar')
end
pmat = S >= 140000;
p = S(pmat)
meanp = mean(p)
end
To call your function, make a new script and put your code to be executed in that script. From what you've shown, it would be like this:
filename = 'Salaries.xlsx';
S = xlsread('Salaries.xlsx')
meanp = mystaff(S); % calls the mystaff function by passing in S
Let us know if this works for you or what further issues you are encountering.
