How to skip [] when add values to a vector variable?

How to avoid having to put [] around the values that are going into the vector variable when using input command?

for i = 1:n;							
   values=input('Enter a value [x y]: ');			
   point=[point; values]							
end

Enter a point [x y]: 2 2

Error using askpoints (line 7)

Error: Invalid expression. Check for missing multiplication operator, missing or

unbalanced delimiters, or other syntax error. To construct matrices, use brackets

instead of parentheses.

% Just alter the below lines in your code
points=cell(1,n); % before loop
points{i}=values; %inside loop
cell2mat(points) %outside loop

Hi,

Thanks for the quick answer.

Still some issue

part of the function

points=cell(1,n);
for i = 1:n;										
   values=input('Enter a point [x y]: ');     
   points{i}=values;
   i=i+1;
end
cell2mat(points)  

Enter a point [x y]: 2 2

Error using function (line 4)

Error: Invalid expression. Check for missing multiplication operator, missing or

unbalanced delimiters, or other syntax error. To construct matrices, use brackets

instead of parentheses.

Added 's'

values=input('Enter a point [x y]: ','s');     

[madhan ravi]

give input as shown

[2 2]
reshape([points{:}],[],2) % change last line to this also remove i=i+1;

Hi,

Have realized that I have to have a matrix instead of vector. ie every input must be on own line

Example:

1 1 input 1

2 2 input 2

3 3 input 3

Do I have to use another way of converting string to the values to the matrix?

[madhan ravi]

values=input('Enter a point [x y]: ')*[ones(1,2)]

str = input('Enter values x y: ','s');
vec = sscanf(str,'%f')
