Oop got it working. Thanks for the references. Haven't tried notebook
yet save to create an admin password. I never liked zork (adventure)
this is like that but I managed this time. Now I just have to discover
how to control the argument types, Tableau matrix in QQ, pr and pc
integers. Thanks.
def nx(Tableau,pr,pc):
newtab=Tableau
nr=newtab.nrows()
nc=newtab.ncols()
if not pr in range(nr):
print('invalid pivot row in function nx')
return 'invalid pivot row in function nx'
if not pc in range(nc):
print('invalid pivot column in function nx')
return 'invalid pivot column in function nx'
pivot=newtab[pr,pc]
if pivot==0:
print('invalid pivot is 0')
return 'invalid pivot is 0'
else:
cellar=range(nc)
for j in range(nc):
if j==pc:
cellar[j]=0 #had this set to null in VB
else:
cellar[j]=-1*newtab[pr,j]/pivot
for i in range(nr):
for j in range(nc):
if i<>pr and j<>pc:
newtab[i,j]=newtab[i,j]+cellar[j]*newtab[i,pc]
elif i==pr and j<>pc:
newtab[i,j]=cellar[j]
elif i<>pr and j==pc:
newtab[i,j]=newtab[i,j]/pivot
return newtab
