Hii all, I am trying to read a large text file with about 1001 rows and 5 columns. And my first row is with strings (#r g00 g01 g10 g11) and the numerics start from 2nd row. And I want to change the numerical values of four columns(g00 g01 g10 g11) in my code to (g00-1 g01-1 g10-1 g11-1) and use it as an input for calculating my equation. This is my text file #r g00 g01 g10 g11 0.025 0 0 0 0 0.075 0 0 0 0 0.125 0 0 0 0 0.175 0 0 0 0 0.225 0 0 0 0 0.275 0 0 0 0 0.325 0 0 0 0 0.375 0 0 0 0 0.425 0 0 0 0 0.475 0 0 0 0 0.525 0 0 0 0 0.575 0 0 0 0 0.625 0 0 0 0 0.675 0 0 0 0 0.725 0 0 0 0 0.775 0 0 0 0.005235893 0.825 0 0 0 0.06846978 0.875 0 0 0 0.310699895 0.925 0 0 0 0.63992878 0.975 0 0 0 0.843685179 1.025 0 0 0 0.966970842 1.075 0 0 0 0.97488415 1.125 0 0 0 1.044026487 1.175 0 0 0 1.009890799
I used this code
fileID = fopen('size_5.txt', 'r');
formatSpec = '%f %f %f %f %f';
N = 5;
C_text = textscan(fileID,formatSpec,N,'delimiter','\t');
C_data0 = textscan(fileID,'%f %f %f %f %f')
frewind(fileID);
C_text = textscan(fileID,'%f %f %f %f %f',N,'delimiter','\t');
fclose(fileID);
h11= (C_data0(:,2))-1; h12= (C_data0(:,3))-1; h21= (C_data0(:,4))-1; h22=(C_data0(:,5))-1;
Can any one help me?
Thank You!!!

You cannot subtract cell arrays. Perhaps you meant to subtract the contents of the cell array?
% Two cells
C = {1}
C2 = {2}
% subtract their contents using {}
C{1}-C2{1}
