I'll be doing a programming subject where the first half will be spent on Matlab then the second half on C. It has a prescribed textbook: https://www.amazon.com/MATLAB-Programming-Applications-Engineers-CL-Engineering/dp/0495668079 which solely focuses on Matlab programming. With all the resources available on the internet, is it really necessary to have such a textbook? Then again it would be easier to have something condensed all in one book, rather than having to filter through web pages, tutorials, etc. Plus I could use it in later courses as a reference...but I'm still trying to justify the cost. Thanks.
