out = max(x); |
The maximum value in matrix x. |
Example
Simple example showing how to find the maximum value of a vector.
?x=linspace(0,3,4); result: 0 1 2 3 ?max(x); result: 3
Simple example showing how complex numbers are treated.
?x = 3 + 4i; ?max(x); ?max(abs(x)); result: 3+4i result: 3 result: 5
Find the maximum field intensity at each frequency point.
# plot the maximum value of an 3D E-field by frequency
E2 = getelectric("3D field monitor");
f = getdata("3D field monitor","f");
E_dim = size(E2); # dimensions of matrix E
data = matrix(E_dim(4)); # make a matrix of size E_dim(4) ie. number of freq pts
for (i=1:E_dim(4)) {
maxVal = max( pinch(E2,4,i) ); # pick out data at a certain freq
data(i)=maxVal;
}
plot(f,data,"Frequency (Hz)","Maximum E intensity");
