How to take input of coordinates of n number of points and store it in different 2x1 matrices?

The loops I am using are as follows but there is some error.

for i=1:n
    x(i)=input('Enter the X-coordinate of node ')
    y(i)=input('Enter the Y-coordinate of node ')
end
C=[x;y]
for i=1:n
    P(i)= [x(i);y(i)]
end

"I know it is bad programming style, but Rohit Raut wants multiple 2x1 matrices P1,P2..."

A cell array already contains those "multiple matrices", which are trivially accessible via indexing.

i'm a bit confused what you really want. If u are ok with multiple 2x1 matrices in a cell array you can just use num2cell(C,1) in your case, it divides a 2 x n matrix into n cells containing each 2x1 matrices
