The roadblock is math I guess(I read the expr tutorial, and I understand what the norm , snorm, in[1], etc means)

but when I see objects that divide, multiply, modulo the hypot, or sine and cosine to the matrix I get confused.

I know what the hypotenuse, sine and cosine are in a triangle, but when applied to these data storage matrices it confuse me,

Would you advice me to take a course on linear algebra like this one

or what do you think about this ?

thanks
