MATLAB: Can i use linspace here?

math

i have 11 numbers that is showed in the form below
e1=(-5)+PP(1:2).*(-5);
e2=(-5)+PP(1:2).*(-5.5);
e3=(-5)+PP(1:2).*(-6);
e4=(-5)+PP(1:2).*(-6.5);
e5=(-5)+PP(1:2).*(-7);
e6=(-5)+PP(1:2).*(-7.5);
e7=(-5)+PP(1:2).*(-8);
……………
size(PP(1:2))=2 1
i would like to type them in a simpler form, and i just transform them into
RR=linspace(-5,-10,11);
for rr=1:11;
    eval(['e',num2str(rr),'=(-5)+PP(1:2).*RR']);
end;
but it's not work, how can i deal with this problem? could someone help me PLEASE!!!!!!!!!!!!!!

The answer is in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
You should do an array instead with no for loop and no separate variables:
e = -5 + linspace(-5, -8, 7);
but I don't know what PP is.
