To me this sound like a homework question. Then please post, what you have tried so far.

The projection of a vector A onto a vector B has the same direction as the vector B, but a different length. When both are parallel, the length of A is not changed. When A and B are orthogonal, the resultung vector vanishes. You need the dot product to calculate this. The details are explained e.g. at Wiki: vector projection.
Please try this and post what you have done so far. If you have a specific question, you will get assistance here.

A function must start with the keyword "function":
function P = projection(A, B)
Then I'd insert a semicolon after the calculation to suppress the output to the command window. The calculations are correct.
