MATLAB: How to create a user defined vector in matlab

user defined vector

I want to create a user defined vector in matlab?

You mean some thing like this?

prompt = 'Enter a vector';
x = input(prompt) ;

Prompt the user to enclose their numbers in square brackets.

Try inputdlg instead.

a = str2num(char(inputdlg('Enter a: ')));
b = str2num(char(inputdlg('Enter b: ')));
c = a*b;
