% REP.m Replicate a matrix % % This function replicates a matrix in both dimensions. % % Syntax: MatOut = rep(MatIn,REPN); % % Input parameters: % MatIn - Input Matrix (before replicating) % % REPN - Vector of 2 numbers, how many replications in each dimension % REPN(1): replicate vertically % REPN(2): replicate horizontally % % Example: % % MatIn = [1 2 3] % REPN = [1 2]: MatOut = [1 2 3 1 2 3] % REPN = [2 1]: MatOut = [1 2 3; % 1 2 3] % REPN = [3 2]: MatOut = [1 2 3 1 2 3; % 1 2 3 1 2 3; % 1 2 3 1 2 3] % % Output parameter: % MatOut - Output Matrix (after replicating) % % % Author: Carlos Fonseca & Hartmut Pohlheim % History: 14.02.94 file created % 22.01.03 tested under MATLAB v6 by Alex Shenfield function MatOut = rep(MatIn,REPN) % Get size of input matrix [N_D,N_L] = size(MatIn); % Calculate Ind_D = rem(0:REPN(1)*N_D-1,N_D) + 1; Ind_L = rem(0:REPN(2)*N_L-1,N_L) + 1; % Create output matrix MatOut = MatIn(Ind_D,Ind_L); % End of function
