## Matlab Toolbox for Finite Frames

I am currently writing a Matlab toolbox for finite frames. Please check back here in 2015.

### Matlab code (NB! Only a Test Example showing Syntax Highlighting)

We want to approximate the sum \sum_{k=1}^\infty 1/k^2=\pi^2/6. This is implemented in Matlab by the following code:

% for loops in Matlab

% Set the number of terms
n=10;

% initialize sum
Q=0;

% summing over k
for k=1:n
Q=Q+1/k^2;
end

sprintf('Approximation with %d terms: Q = %0.10g',n,Q)

Modify n=10 in line 4 to obtain better approximations.

1. % for loops in Matlab
2.
3. % Set the number of terms
4. n=30;
5.
6. % initialize sum
7. Q=0;
8.
9. % summing over k
10. for k=1:n
11.     Q=Q+1/k^2;
12. end
13.
14. sprintf('Approximation with %d terms: Q = %0.10g',n,Q)
% for loops in Matlab

% Set the number of terms
n=10;

% initialize sum
Q=0;

% summing over k
for k=1:n
Q=Q+1/k^2;
end

sprintf('Approximation with %d terms: Q = %0.10g',n,Q)
