hi i want to know how to arrange the 1000 different values in ascending order in matlab? is there any command to arrange it in ascending order?

Best Answer

The sort command can sort in ascending and descending order. See "help sort".

MATLAB: Ascending order-room modes

Your code can be vectorized to:

c  = 344; % speed of sound (m/s)
w  = 2.20;
L  = 3.50;
h  = 3.02;
% AXIAL MODES
n = 1:9;
fL = c/2 .* n/L;
fw = c/2 .* n/w;
fh = c/2 .* n/h;
% Tangential modes
nL = 1:4;
nw = 1:4;
nh = 1:4;
fLw = c/2 * sqrt(bsxfun(@plus, (nL.'/L).^2, (nw/w).^2));
fwh = c/2 * sqrt(bsxfun(@plus, (nw.'/w).^2, (nh/h).^2));
fLh = c/2 * sqrt(bsxfun(@plus, (nL.'/L).^2, (nh/h).^2));
% Oblique Modes
fLwh = c/2 * sqrt(bsxfun(@plus,(fLw(1:2,1:2) * 2/c).^2, permute(nh(1:2)/h,[3 1 2]).^2));

In your previous code you didn't preallocate correctly for the tangential modes and oblique ones.
Also the fLh depends on nL and nh but its calculation is nested into the loop for nw as well, which means that you calculate it several times redundantly overwrtiting the same results.

Now the MAIN question:

- Do you want fL,fw,fh,fLw,fwh,fLh and fLwh all together sorted?

EDIT

[srt, idx] = sort([fL(:);fw(:);fh(:);fLw(:);fwh(:);fLh(:);fLwh(:)])
