How to simplify code with multiple variable names?
显示 更早的评论
For example, a code like this:
ma1 = trapz(ea1(r1:ir1),ty(r1:ir1));
ma2 = trapz(ea2(r2:ir2),ty(r2:ir2));
ma3 = trapz(ea3(r3:ir3),ty(r3:ir3));
ma4 = trapz(ea4(r4:ir4),ty(r4:ir4));
ma5 = trapz(ea5(r5:ir5),ty(r5:ir5));
But, if I have even more variables, then is there a shortcut or simpler method to syntax them?

Yeah, don't create the sequentially-numbered arrays ea, r and ir in the first place.
What specifically should use instead will depend upon where they're coming from, but since each ea is being addressed as a vector, then simply storing ea as a 2D array might work if they're different variables at each and there are the same number of observations for each.
Are the X spacings (ea) nonuniform one must presume for each?
Are the number of elements in each subset the same?
So many questions, so little detaill...

"How to simplify code with multiple variable names?"
By using arrays rather than multiple variable names.

You can use arrays to hold your data. So one approach would be to use arrays:
ma - n by 1
ea - k by n
r - n by 1
ir n by 1
then you could loop through the values
n = 5;
ma = zeros(n,1);
for i = 1:n
ma(i) = trapz(ea(r(i):ir(i),i),ty(r(i):ir(i)));
end
