Hi, You can use ones as well if the array (not matrix) has the same values, or the array function to create an array from a sequence, or matrix for matrix and a sequence of sequences a = n.ones((3,5)) * 99999 b = n.array((1, 2, 3), (4, 5, 6), (6, 7, 8)) c = n.matrix((1, 2, 3), (4, 5, 6), (6, 7, 8)) Matthieu 2007/12/21, devnew@gmail.com <devnew@gmail.com>:

hi i am a beginner with numpy and python,so pardon me if this doubt seems silly i want to create a matrix with say 3 rows and 5 columns..and then set the values of each item in it .for this i did something like below

myarray=zeros((3,5)) #then set the items for row in range(3): for col in range(5): myarray[row][col]=999999.9999

mymatrix=matrix(myarray)

is this the way to do the matrix creation and value setting? is the use of zeros() unnecessary? i am in the early learning stage so your reply wd help me much
