Hi all,
I need to enter by keyboard some values and them use for loop for them so that matlab should know the number of them automatically.. So, How to enter multiple number of input values (let us say n) seperated with commas or space ? I tried the function input , but it doesn't work for n number of inputs because it include the space or comma as a length of the string
n=input('enter the value of quereis','s')

n=input('enter the value of quereis','s')
if separated with comma
out=regexp(n,',','split')

it do works. Just give the input in [2 3 4] brackets.

Note that Jwana used the 's' option of input, which reads input as a string. The 's' option has to be removed for Harshit's answer to work.

values = input('enter the value of queries')
and have the user type input such as
[5 13 9 -5 6]
including the []. The user could include commas.
Or,
valstring = input('enter the value of queries', 's');
valparts = regexp(valstring, '[ ,]', 'split');
values = str2double(valparts);
in which case the user would not need to use [] around the values, and could use space or comma.

Ah, I just re-read the question and see that you want to enter by keywords. In that case, the variable "valparts" above will have the answer. valparts{1} would be the first word, valparts{2} the second, and so on.
