Creating a for loop that calls to a separate function script and collects outputs in vector

I have a function file called AirProperties.m that takes an Altitude and Mach Number as input and spits out 7 characteristics of the air in a row vector.

What I want to do is create a script that passes a vector of Altitude and a vector of Mach Number (of any size n) through AirProperties.m and have the output collected in a vector (n rows by 7).

Here is where I struggle. I want to evaluate AirProperties at the first Altitude value and every Mach Number, then the next Altitude value at every Mach Number.

This is what I have and it's not much:

% Inputs of Altitudes and Mach Numbers
n = 100;  % Number of values
Alts = linspace(0,100000,n); % 100 values
Machs = linspace(0.5,5,n);   % 100 values

% initialize vector to collect results
Results = zeros(n,7); % = [alt Me ReL Ue Cfe kadm Ra] The variables in the output of AirProperties.m


for i = 1:n
    Results(i,:) = AirProperties(Alts(i),Machs(i));
    for j = 1:n
    Results(j,:) = AirProperties(Alts(j),Machs(j));
    end
end

In this scenario, with 100 altitude values and 100 mach number values the size of the output vector would be 10000 by 7.

It's been a while and I know I'm missing some for loop basics in my brain, but a nudge in the right direction would be appreciated.

One simple approach:

cnt = 0;
Results = nan(n*n,7); % preallocate 10000x7
for ii = 1:n
    for jj = 1:n
        cnt = cnt+1;
        Results(cnt,:) = AirProperties(Alts(ii),Machs(jj));
    end
end

It might make more sense to store the data in a 7xnxn array:

Results = nan(7,n,n); % preallocate 7x100x100
for ii = 1:n
    for jj = 1:n
        Results(:,ii,jj) = AirProperties(Alts(ii),Machs(jj));
    end
end

Then the 2nd and 3rd dimensions trivially correspond to the Alts and Machs respectively.

Thank you. This works well.
