function input = inputmatrix(matrix,dx,dy)

% creates a matrix of the form 'input' = [x1 y1 value1;x2 y2 value2; ...]
% from a matrix of the form 'matrix' = [value11 value12 ...; value21
% value22...;...]. dx and dy describe the distance between two values in x
% or y direction.
%
% usage:    input = inputmatrix(matrix,dx,dy)
