function [a,b] = c(d,e)
a = d+e;
b = d.*e;
The following MATLAB script utilizes a local function and the c function mentioned above. Compute the final value of vector a. Please show how you obtained your answer. Could someone explain it how to get a briefly? Thank you in advance.
a = [1 2];
a = compute(a);
function a = compute(b)
[a,b] = c(b,b);
end

I would like to determine final value of vector a.

Isn't "the final value of a" the output of the compute function?

Ran in:
a = [1 2];
a = compute(a)
a = 1×2
2 4
function a = compute(b)
[a,b] = c(b,b);
end
function [a,b] = c(d,e)
a = d+e;
b = d.*e;
end
Not sure what you consider the "final value of a". Do you mean a(end), which would be 4?

@Sam Yeoh: I do not see a multiplication by 2. Do you mean the output "1x2"? This means, that a is an array with the dimensions [1, 2]: One row, 2 columns.
