can i use linspace here??
显示 更早的评论
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!!!!!!!!!!!!!!

As IA pointed out, Don't program in MATLAB this way! Learn to use MATLAB the way it was designed to be used. Rather than making many separate variables, make one variable that holds all the same information. For this task you can use an N-D array, a structure or a cell array.

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.

e = -5 + @bsxfun(@times, PP(1:2), linspace(-5, -8, 7));
then your e6 (for example) would be e(:,6)
Note: this code relies on P(1:2) being a column vector.
