Hello, I am beginner at MATLAB and I am trying to plot a graph by some datas from a text file but I get this error message.

These are codes that i wrote;

clc;
clear;
[names,a,b,c,d]=textread('nums.txt','%s %d %d %d %d')
T=200:20:400
CpSO2=a(1)+b(1)*T+c(1)*T.^2+d(1)*T.^3;
CpSO3=a(2)+b(2)*T+c(2)*T.^2+d(2)*T.^3;
CpO2=a(3)+b(3)*T+c(3)*T.^2+d(3)*T.^3;
CpN2=a(4)+b(4)*T+c(4)*T.^2+d(4)*T.^3;
plot(T,CpSO2)
hold on
plot(T,CpSO3)
hold on
plot(T,O2)
hold on
plot(T,N2)

Thanks for your helps.

在 MATLAB Online 中打开

The issue maybe that your current directory of MATLAB file and the directory your 'nums.txt. files is saved are different. For this you need to specify complete path of yout file. For example:

[names,a,b,c,d]=textread('C:\Users\PULKIT\Desktop\nums.txt','%s %d %d %d %d')

In my case I saved the file on my desktop. You can see the exact path by right clicking on the file and going in Properties (in case you are using windows).

So is it solved (no errors), or not???

Attach 'nums.txt' if you need more help. save() and load() are fine if you're just going to use MATLAB but if you want to look at them in a text editor or some other program you might want to still save them as a text file.
