How to find the position of an element in a vector

Hello,

Is there a function in matlab that takes a column vector of n rows and a number as an input and returns its position in the vector,

for example a vector x as given below, suppose I want to find the position of number 2 in x. I want the answer to be in the form of [ 1 4]

x=[2 3 4 2];

I thought of the following code

x=[2 3 4 2];
for i=1:4
if x(i)==2;
pos(i)=i;
i=i+1;
end
end

But the output is of the form

[1 0 0 4]
