Problem 135. Inner product of two vectors
I think it would be helpful if you specified whether the vectors are row vectors, column vectors, or whether they can be an arbitrary mixture. The test suite only has row vectors, but this makes it rather trivial.
If the x and y vectors could be row and column vectors, then bsxfun(@times, x, y) does a better job
Test set should include some column vectors.
if you make the example-function "y = fcn(x,y)
z = x*y", please make sure matlab at least handles it; "z = fcn(x,y)
z = x*y" would be preferred =)
This function already exists, look up the dot function
In the given code snippet, make some changes to correct the function definition. (The first line)
Tricky on the variable to return... not sure if it was for teaching how-to-debug purposes.
funny, after all.
Remember to edit the return variable (change it from y to z)
LOOK FOR 'y' IN-LINE 1
CHANGE IT TO 'z'!!!!!!!!!!
