Most assignments require capability that you do not want to implement yourself. Thus you have to link against libraries. I will provide my version of tools that you can use to do the assignments. The TA and I will provide support for these. Some specific routines that you may want to look at for each assignment are listed at the end of this page.
To get you started, there is an example program showing the use of a few functions here . There are hopefully enough comments in example.c to get you started. The files compile_line (C) or to get you started. The files compile_line++ (C++) deal with the complexities of including and linking on the graphics machines. The files matrix.txt and image.tiff can be used as example data for the program.
Compile lines for various other machines (C):
linux_x86_64_c2 (e.g. graphics machines)
linux_386_p4 (e.g. basic 32 bit intel)
linux_x64_opteron (e.g. lectura)
linux_386_athlon
linux_386_xeon

Start with a "man kjb" or the above link. Note that the first part of the document is a bit overwhelming, as it is geared towards writing substantive vision copmponents shared with the group and/or, writing code for the library itself. This document essentially gives you a template for the "INCLUDE AND LOAD" strategy described by "man kjb".
A key point is that "man kjb" gives a machine generated list of all routines which have at least minimal documentation. (Perhaps 1/2 of the routines of interest are documented.)
Note that there are man pages for the main data types. In particular, you can do:
man Vector
man Matrix
man KJB_image
man Pixel
(Either click on the link or use the "man" command.)

I wrote it a few years back--hopefully it is not too out of date.
Specific routines for assignment two
For assignment one you might want to look at the man pages for:
read_matrix
get_random_matrix
multiply_matrices
max_matrix_element
ow_multiply_matrix_by_scalar
ow_subtract_scalar_from_matrix
ow_add_matrices
plot_open
plot_matrix_cols
get_MP_inverse
constrained_least_squares (grad students only)
(Either click on the link or use the "man" command.)
You will also want to use something like prompt_to_continue() so you (and the TA) can actually look at your plots. (This is used in the example program linked above).
For assignment three you might want to look at the man pages for:
multiply_by_transpose
multiply_with_transpose
diagonalize_symmetric
KJB_image (case sensitive; there is also a kjb_image(1))
Pixel
kjb_read_image
kjb_write_image
(Either click on the link or use the "man" command.)
For assignment four you might want to look at the man pages for:
least_squares (OK now that you know how to do it).
plot_open3
plot_matrix_values
(Either click on the link or use the "man" command.)
For assignment five you might want to look at the man pages for:
kjb_read_image
kjb_write_image
kjb_display_image
ow_make_black_and_white_image
bw_image_to_matrix
matrix_to_bw_image
get_1D_gaussian_mask
get_2D_gaussian_mask
x_convolve_matrix
y_convolve_matrix
convolve_matrix
(Either click on the link or use the "man" command.)
