Hello,
I have textfile, which has 3 columns of 73 rows each. I want to plot it on the graph. I am using the following command for the same
fid=fopen('error10.txt');
s=textscan(fid,'%g %g %g');
fclose(fid);
x1=s{1};
x2=s{2};
x3=s{3};
y=-1:0.05:1;
plot(x1,y,x2,y,x3,y);
But when I use this command I get the following error
Error using textscan
Badly formed format string.
How do I solve this. I tried different format:%f, %e gave the same error. %d gave output in 0, 1 and -1. My textfile is as follows:

X = load('error10.txt');
y = -1 : 0.05 : 1;
plot(X(:, 1), y, X(:, 2), y, X(:, 3), y);

This has nothing to do with your original question. The problem is that the y is your example does not have the same number of elements as the number of rows in your textfile.
Only you know how to generate that y. One possible way:
y = linspace(-1, 1, size(X, 1)); %no idea if it's appropriate or not.
