how to connect two functons in matlab

I am want to connect two functions: In first function(firstf.m),i want to make a 'for' loop to variables p,r then I calculat [s] for each value then i use this value in second function accuracy that should repeat 100 time The first function is

 [s] = firstf(data,k,opts)
 p = 30;
 if isfield(opts,'p')
    p = opts.p;
 end
 for r = 20:22;
 if isfield(opts,'r')
    r = opts.r;
 .
 .
 .
 .
 [s] = k_means(U,k)

first how to make for loop for variables p,r in first function and take every [s] (output of first function ) to calculate accuracy (second function) that should repeat 100 times

muhammad - are opts.p and opts.r arrays? Do you expect to iterate over these arrays to get the individual elements that you will use to compute the s which you will then pass to the second function 100 times?

It isn't clear (from the above) why you start to iterate over 20,21,22 using the indexing variable of r which you then override with opts.r. Please provide more details and the signature of your second function and describe how it is to be used. I understand that we provide s to this function and that it must return something (the accuracy) but then do you feed that accuracy back into the second function?

[muhammad ismat]

the first code

[s] = firstf(data,k,opts)
p = 30;
r = 20;
.
[s]=k_means(U,k)

and the second function

Accuracy=ya(data,x)
.
.
[s] = firstf(adj,x)
.
A = s(linindices);
Accuracy = mean(auc)

i want to variables p and r to take range of values and in each time calculate s using first function then calculate accuracy using second function then return to first function to take next values to variable p ,r and calculate s and so on.

[Geoff Hayes]

But why is p 30 and r 20? How do you intend to make a 'for' loop to variables p,r as you stated in your question? It isn't clear to me how p and r change over time or iterations. Do you obtain p and r from arrays or from something else?

As for the second function, why does it call the first function? I thought that you wanted to pass the s from the first function into the second function.

[muhammad ismat]

 p=30 and r=20 is random i want to p=1:100 and r=1:100 
to obtain the better s and calculate better accuracy

[Geoff Hayes]

It sounds like you may have two loops here

 for p=1:100
    for r=1:100
        % do something to calculate s
        % refine s
    end
 end

Is the above correct? Also, please answer my second question as to why the second function calls the first one.

[muhammad ismat]

but in previous code i obtain on only final value of s so when i transfer to second function (another program) i obtain on only value of accuracy

[muhammad ismat]

in above code how to obtain all values of s (saved)

[muhammad ismat]

the above code not required but the second function calls the first to calculate accuracy that its calculation depend on the value of s

@muhammad: I still do not understand, what you want to achieve.
