Hey everybody,

I have a space delimited textfile and would like to know how to make 1*5 cell with tline.

With below code, it shows the 1*40 cell. Is there a way to make the 1*5 cell?

clear; close all; clc;

tline = 'no 1 -5 21 -5'; % imported text example

tt = split(tline,[" ",","])';

在 MATLAB Online 中打开

tline = 'no      1           -5           21           -5';           % imported text example
tt = regexp(tline, '\s+', 'split')
tt = 1×5 cell array
    {'no'}    {'1'}    {'-5'}    {'21'}    {'-5'}
