I want to concatenate 32 columns from different 32 files sequentially named. The code works fine if the the 32 files have similar size arrays(2500 in some of the sets); however, other sets of 32 files have one file of size 2909 or more. Now I need to consider all the concatenation to be over the first 2500 only. Please help in editing the code below (error message is below as well):

clear all size=2500; for i=1 : 32 filename=horzcat(pwd,'\Run4915_Inj',int2str(i),'.pre'); delimiter = {'\t',','}; startRow = 3; %% Format string for each line of text: formatSpec = '%f%f%f%*s%[^\n\r]';

%% Open the text file. fileID = fopen(filename,'r');

%% Read columns of data according to format string. dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'HeaderLines' ,startRow-1, 'ReturnOnError', false);

%% Close the text file. fclose(fileID); %% Create output variable time(:,i)=dataArray{1:size, 1}; P(:,i)=dataArray{1:size, 2}; needle(:, i)=dataArray{1:size, 3}; Pav=mean(P,2); nav=mean(needle,2); tav=mean(time,2); %% Clear temporary variables clearvars filename delimiter startRow formatSpec fileID dataArray ans; end

I get this error as I run the code to the exceptional set:

Unable to perform assignment because the size of the left side is 2500-by-1 and the size of the right side is 2909-by-1.
