MATLAB: How to index from three vectors

indexing find

Hi,

I think this is quite simple but I'm missing something.

I have three vectors

A = [0 1 0 1 0 0]'
B = [0 1 1 0 0 0]' 
C = [0 1 0 1 0 0]'

I want to index to get the location where there is a 1 in all vectors and the same so I would want this to tell me 2 as that is the location in all three that is equal to 1. I know find will work for two vectors but how to you write it for three?

Thanks for any help.

find(A==1 & B==1 & C==1)

MATLAB: Re-sizing vectors

If you want to change the range of the y-values, you can do it by first normalizing and then denormalizing to your required range

x = [1xn signal]
xNormalized = (x-min(x))/(max(x)-min(x))
newMin = 0;
newMax = 90;  % new minimum and maximum value of the signal you want
xNew = xNormalized*(newMax - newMin) + newMin;

xNew will have same shape of x but varies from newMin to newMax.
