MATLAB: How to correctly store output from this For loop into a new variable

arrayfor loopMATLABnew variableoutput

Hi!
I have a simple for loop im trying to write, wherein within an array from 1:5:150, if a number is even it is multiplied by 4 and if odd it is cubed:
a=[1:5:150]
for a=1:5:150
    if rem(a,2)==0; i(a)= 4*a
    else i(a)= a.^3
    end
end
The output here is set to place all the modified values into a new variable ,i, however this produces a column list with intervals of 4 zeros between each value as such:
Columns 1 through 13
           1           0           0           0           0          24           0           0           0           0        1331
How can I produce a single row vector output instead so that the new variable represents the output in a much neater way?

Lots of problems with that code. Just try it this way:
a=[1:5:150]
for k = 1 : length(a)
	if rem(a(k),2) == 0
		output(k) = 4 * a(k);
	else
		output(k) = a(k) .^ 3;
	end
end
output
