bin2Q(x,intsize)

function y = bin2Q(x,intsize)

% bin2Q
% 
% Converts binary data of any format in a string to floating point
% decimals of a defined fraction size. the intsize input parameter defines
% the size of the exponent and sets the fixed point location in the binary
% number. se accompanied matlab program for test of this function
