How to create nested loop?

Hi

Currently i am writing a program in MATLAB. In the program i have some indexed values that i want to use for further analysis. The indexed vales under the variable name toggle(idx.maxpts) are as follows:

ans =

1.0e-08 *

0.0844

0.1368

0.3354

0.7585

In the program i want to create a nested loop where i want to apply some equations to the first values and apply some equations to the third and fourth values and save the results. Once i have the output i want to apply some other equation to get the desired result. Thank you, any help is highy appreciated.

A demonstration of nested for loops in MATLAB:

A = magic(5);
disp(A);

    17    24     1     8    15
    23     5     7    14    16
     4     6    13    20    22
    10    12    19    21     3
    11    18    25     2     9

[m,n] = size(A);
for ii = 1:m
    for jj = 1:n
        disp(A(ii,jj));
    end
end

Hi Benjamin. Thank you for your answer. However i want to know how can i apply different equations for diferent elements in nested loop as i mentioned in the question above.

[Voss]

eqn = { ...
    @(x)x^2 ...
    @(x)x^3-2*x ...
    @(x)sin(x)+exp(-x) ...
    @(x)cos(x)^2-abs(x) ...
    @(x)cos(x)^2+sin(x)^2 ...
    };
A = magic(5);
disp(A);

    17    24     1     8    15
    23     5     7    14    16
     4     6    13    20    22
    10    12    19    21     3
    11    18    25     2     9

[m,n] = size(A);
for ii = 1:m
    for jj = 1:n
        disp(eqn{ii}(A(ii,jj)));
    end
end
