Lua Matrix libray, in the spirit of Matlab

Dependencies:

• depends on https://github.com/thenumbernine/lua-ext
• matrix.ffi depends on LuaJIT, otherwise this works with vanilla Lua
• matrix.lapinv depends on https://github.com/thenumbernine/solver-lua (which itself depends on this project)
• matrix.ffi has optional LAPACKE support which depends on https://github.com/thenumbernine/lua-ffi-bindings and on LAPACKE as well
• if you use a complex type with matrix.ffi then this library is required: https://github.com/thenumbernine/complex-lua

Example:

matrix initialization:

m = matrix{1,2,3}

m = matrix{{1,2},{3,4}}

m = matrix(n)

etc

m = matrix.const(math.pi, 2, 3)

m = matrix.const(math.pi, {2,2})

gives you a 2x2 matrix filled with the value for pi.
