## 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)

% 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.

Approximating pi square over 6

- % for loops in Matlab
- % Set the number of terms
- n=30;
- % 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)
