LinSolve Syntax and Documentation

[chris.bragg]

There is a function "linsolve" (aka LinSolve) referenced both in the user guide and the system "help" system. While there are alternative functions (Solve2x2 and Solve3x3) that work as documented, LinSolve does not seem to work as intended. See the attached images, Namely the "User Guide", the system "Help" and a screen shot showing my attempts at marking the function work. Have I missed something here?
