linear algebra notation
i started Linear Algebra today and my teacher has a thick accent. To make it worse he doesn't explain what these new notations mean.
i cant find the latex code for systems so if anyone knows it please lemme in
i understand generally what the equation is showing but the subscripts are terribly confusing to me.
second off Im pretty sure some of those i's are 1's but i couldnt tell the difference on the chalk board.
Could it be simply
a11 x1 + ... + a1n xn = b1
am1 x1 + ... + amn xn = bm
A system of m linear equations in n unknowns?
