input comma separated values to a matrix

Question

0 个投票

I need a shove in the right direction:

How do I ask the user for some numerical values that are separated by a comma? For example "Enter the numbers, separated by a comma"

Then the user would enter "1,2,3" and these numbers would go into a matrix

Second question: There isn't a go to statement in Matlab, right?

Of course it can be done.

clear; clc;
answers = input('Enter the numbers, separated by a comma : ','s');
str = regexprep(answers,',',' ');
num = str2num(str)

And about go to statement, Matlab don't have go to statement.

Many thanks. I had not idea where to start. All I have is a Matlab textbook and this forum.

You could also use

num = strread ( answers, '%f', 'delimiter', ',' );
