Learning Python --Beginner Question

Hey All,
I am translating a whole lot of code from MATLAB to Python/NumPy/SciPy. However, I am having a lot of trouble creating column vectors. I know that in MATLAB it would go like this:

a = [1,2,3,4,5,6,78], colvec = a'

if anyone know the answer of has any good hints, please answer!

thanks!

numpy.transpose(...)

okay. good. that works, so thank you very much.

naturally, a new problem has presented itself. i think this one is somewhat more complicated.

i have an image.tif that i am trying to open as a matrix in python. i learned about the Image.open(...) but i get an error when i try to do this.

i typed in:

from Image import Image
im = Image.open('C:\...tif')

I get back:

AttributeError
C:\Users\student\Desktop\(<python console> in <module>()
AttributeError: class Image has no attribute 'open'


help?

thanks

I'm not sure tif images are supported by PIL. I've read conflicting information. A work around would be to use imagemagick to convert the tif to a png and then use matplotlib or PIL to open the image. See http://matplotlib.sourceforge.net/users/image_tutorial.html for an example.

numpy.transpose(...)

you can also use a.T
Also, you may want to keep a copy of Numpy for Matlab user handy.

I'm not sure tif images are supported by PIL.

According to the documentation, http://www.pythonware.com/library/pil/handbook/format-tiff.htm is supported.
Are you sure that you've instantiated the object correctly and given the correct object path?

Also, I think your import statements might be wonky, and that could be throwing off your references. Try
Import Image
Image.open
and
from PIL import Image
Image.open
