If anything, saying that C++ has no support for linear algebra is giving it too much credit. C++ has an abundance of libraries that are broken in various strange and marvelous ways. Typically, you find out about the brokenness only after you made the investment of learning the library and put it into production, so that there is no way back. Your comment about valarray is a good example of this.
