This and the book by Mary Boas are my favorite books for mathematical physics. It says it is for engineers also, which I suppose is ok, but the emphasis seems to be for physicists. For example, the treatment of Laplace and Fourier transforms is fine, but I would have expected more in a book intended for (electrical) engineers.<br>Having said that, the authors have a knack for taking complicated material and explaining it clearly and concisely, with some added insight thrown in for good measure. And if it seems like a big book, then fine with me - more for the money.
