How does this save time? Function calling overhead makes this computationally slower than direct multiplication. Typing the function call degrees(theta) is 14 keystrokes whereas 180/pi*theta is only 12 keystrokes. The same is true for typing radians(theta). So how does this save time?

Hi, thanks for your feedback. This file was written well over 4 years ago (before you reviewed it) and at the time there was nothing available that did this. As with all my files they were simple (in my mind) solutions to achieve what I wanted and worked. I posted them in case anyone else found them useful. Perhaps you might consider that in future when rating (very!!) old submissions ;-)

Also works for 5.3

Great

Thanks

Alternatively you can avoid the double loop and reduce the code to the following line:

c2c = nan(size(i,1), size(i,2)); c2c(sum(i, 3)==765) = 2; c2c(sum(i, 3)==0) = 1;

This works great, and I used it with dec2bin first.

Worked great for our lab, and keyed us in to a problem we were having with multiple input-output devices installed. Thanks!

good yar

Awesome

What is Rasmus review's one liner? Can you post it here please?

Thanks.

should there be an "a whole" joke here?

to complicated for simple function

Good for beginners! Thanks

Great and simple. Thanks.

I think this is an improvement over uisetcolor because it's a bit more elegant--you can set your own palette, it's more compact, and you don't have to redundantly press 'return' after selecting the color. -Kevin

Hi I found the lack of a COUNT command quite astonishing. The problem with the solutions offered here is that they 'deliver more than needed' (i.e. position of the element). On a CPU instruction level, this requires an unneeded write to RAM, where an CPU register increment would suffice for the purpose of COUNT. I made three tests with a vector of 64800 elements:

Option 1:
if 1== 1
tic
sum(listeNZ==8)
toc
end

1603 occurences of 8
elapsed time: 0.0051

Option 2:
if 1== 1
tic;
length(find(listeNZ==8))
toc
end

1603 occurences of 8
elapsed time: 0.0038 !!!!!!!! :o (about 30% less time needed)

just for fun:
Option 3:
if 1==1
sums=0;
tic;
for k=1:64800
if listeNZ(k)==8
sums=sums+1;
end
toc
end

1603 occurences of 8
elapsed time: 0.1401 !!!!!!!! :O (about 40 times slower than option 2)

In conclusion, the times needed are too small to worry about, but a COUNT command should really be included in the standard nevertheless... I am really astonished that the length(find()) combo is faster than the sum(), though...

thank you so much. you helped me out a whole lot.

tfg

it is a tooooooooooo greate

What's so different with this from the matlab's intrinsic UISETCOLOR function in uitools?

Yes - this is a problem that really irritates me as well.

I can't figure out why this is at the moment, but if I do I'll post an update.

It doesn't seem to affect other programs e.g. VB.

If you are intending to use this function with winsound devices, it is highly reccommended that you download the WinsoundHwInfo function as well. The Winsound HWinfo function is a fix for a problem with the daqhwinfo function in the DAQ toolbox where in some circumstances it returns incorrect boardIDs for output channels.
