for loop/functions

Hi

I'm stuck on a certain problem I'm trying to solve.

I'm running a for loop with an array of 90 values. These values are passed to a function I created. I need to record every value that the function produces (I'm thinking within an array). I just cannot seem to work out how to do that.

I also have another for loop running with another 90 values, passed to the same function and need to do the same with these values.

The 2 sets of data then need to be put into a 2D array (I also can't seem to work this part out either). Am I best getting each data set into separate arrays first? Then into a 2D array? Am I also correct that these two data sets cannot be put into a 2D array unless they are the same size?

Thanks

Bob

show us what you;ve tried - you'll get better help that way.

There's no reason why you can't assign the output of a function to an array

% initialize an array
A = zeros(100,2);

for nn = 1:100
    A(nn,1) = times(nn,nn+1);
    A(nn,2) = sum(1:nn);
end

Is this what you asking?

[Wayne King]

function() outputs a scalar? B is a number. Also, function() is only set up to take r as a scalar?

[Wayne King]

You didn't answer my question about B, if B is a scalar. Still it sounds like what I suggested works:

put your r values in a vector, let's assume it has length 100

B = zeros(100,1);

for nn = 1:100

s = r(nn)/2;

B(nn) = function(r(nn),angle,s);

end

max(B)

[Wayne King]

Bob, in your code example you showed inputting the angle as a vector. does your function only accept a single angle at a time? Then do this.

B = zeros(91,1);

anglez = 0:90;

for nn 1:91

B(nn) = function(r,anglez(nn),s);

end

[Wayne King]

Given that I know absolutely nothing about your function(), I cannot possibly speculate on what the function is doing.
