示例1: _RLSortRoots
# 需要導入模塊: import scipy [as 別名]
# 或者: from scipy import zeros_like [as 別名]
def _RLSortRoots(mymat):
"""Sort the roots from sys._RLFindRoots, so that the root
locus doesn't show weird pseudo-branches as roots jump from
one branch to another."""
sorted = zeros_like(mymat)

sorted[n, :] = row
else:
# sort the current row by finding the element with the
# smallest absolute distance to each root in the
# previous row
available = list(range(len(prevrow)))
for elem in row:
evect = elem-prevrow[available]
ind1 = abs(evect).argmin()
ind = available.pop(ind1)
sorted[n, ind] = elem
