mbase2dec

function dec=mbase2dec(s, mbase)
% Convert integers in muitiple bases to decimal integers. It is the inverse
% function of DEC2MBASE.
%
% DEX=MBASE2DEC(S, MBASE) has the following inputs and output.
% Inputs:
%    S,    a matrix of size M by N where M is the length of DEC and N
%          is the length of V.
%
%    MBASE, a vector of bases, such that
%           sum(S.*MBASE(ones(N,1),:),2)==DEC is true, where N=size(S,1).
%
%    Both S and MBASE should be the outputs of DEC2MBASE.
%
% Output:
%     DEC,   an array of decimal integers.
%
%
% Example, if s=[7 1 703], mbase=[8192 1024 1] then
%
%             dec=mbase2dec(s,mbase)
%
% gives dec=59071
%
% See also DEC2MBASE.

m=size(s,1);
dec=s.*mbase(ones(m,1),:);
dec=sum(dec,2);
