I have written a code to implement a poincare index technique in matlab.Now that,I have to convert the code into C ..Please help me out..Here is the code:

function [PC,AR] = poincare_index_v1(theeta)

[rows cols] = size(theeta);
Np = 24;
PC = zeros(rows, cols);
AR = zeros(rows, cols);

for i = 4 : rows-4
    for j = 4 : cols-4

          bx = [i-3 i-3 i-3 i-3 i-3 i-3 i-3 i-2 i-1 i i+1 i+2 i+3 i+3 i+3 i+3 i+3 i+3 i+3 i+2 i+1 i i-1 i-2 i-3];
          by = [j-3 j-2 j-1 j j+1 j+2 j+3 j+3 j+3 j+3 j+3 j+3 j+3 j+2 j+1 j j-1 j-2 j-3 j-3 j-3 j-3 j-3 j-3 j-3];

          delta = 0;
          for k = 0 : Np-1
              indx = mod((k+1),Np)+1;
              partial_del = theeta(bx(indx),by(indx)) - theeta(bx(k+1),by(k+1));
              if(partial_del < (pi/2))
                  del = partial_del;
              elseif (partial_del <= (-pi/2))
                      del = pi + partial_del;
                  else
                      del = pi - partial_del;
              end
              delta = delta + del;
          end
          PC(i,j) = delta / (2*pi);
  %         if(PC(i,j)==(3.533949646070574e-17))
  %             AR(i,j)=1;
  %         end
          if(PC(i,j)>=0.45 && PC(i,j)<=0.55)
      AR(i,j)=1;
          end
  if(PC(i,j)<=-0.45 && PC(i,j)>=-0.55)
         AR(i,j)=2;
  end
      end
  end

end

Hello if you explain to me the code and/or algorithm may be I can help you to convert into C

Unless this question is about using matlab coder (for which I can't help), this is not appropriate for this forum.

This is a matlab forum not a C forum.

Furthermore, if you can't convert that basic code (in that it is simply loops and indexing with no high-level functions used) into C on your own, perhaps learning the basics of C is in order?
