How to initialize my array directly using variables ?
It could also be that I wanted:
test11 = 1
test12 = 1.5
test13 = 2
test21 = 0
test22 = 5
Dx = numpy.matrix('test11 test12 test13; test21 test22 -0.5; 0 -0.5 1.5')
Etc... for many variables...
Appreciate ANY help, thank you

Why not just use the list-of-lists constructor instead of the string
constructor?
m = numpy.matrix([[1,2,3],[4,5,6],[7,8,test]])
