How to do computation in local function?

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

@Sam Yeoh what exactly is your question? Have you tried to run the above code to see what the output is?

[Sam Yeoh]

I would like to determine final value of vector a.

[Geoff Hayes]

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

Answer 1

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?

May I ask why multiply it by 2?

@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.
