Remarks on the MATLAB assignments:



Several MATLAB problems need commands which are non-standard. These

commands require certain M-files which can be found on the webpage for MA265.



1. In Section 1.2, a set of matricies is needed. These matricies 

are written in the M-file "matdat1.m".



2. In Section 1.5, the command "rowop" requires two M-files: 

"rowop.m" and "mat2strh.m". 



3. In Section 1.6, the command "invert" needs the M-file "invert.m".



4. In Section 3.1, the M-file "dotprod.m" is needed.



5. In Section 3.4, the command "gschmidt" can be used to obtain an

orthonormal basis. The M-file "gschmidt.m" is needed.



6. In Section 3.5, the command "project" can be used to view the

projection vector. The M-file "project.m" is needed.



7. In Section 3.6, the command "lsqgame" can be used to compute and to view the 

lease square line fit of a set of data. The M-file "lsqgame.m" is needed.



8. In Appendix B, the problems are for complex numbers. The command "rowop" 

is used again but the row operations can be performed in the command window.
