Here we prove the theorem about linear transformations from Rn to Rm. Theorem. A function f from Rn to Rm is a linear transformation if and only if it satisfies the following two properties: For every two vectors A and B in Rn. f(A+B)=f(A)+f(B); For every vector A in Rn and every number k. f(kA)=kf(A).
REXX was a computer programming language developed at IBM in the late 1970âs. Itâs a structured high-level language intended for scripting and macro writing. It was popularized in the Amiga computer operating system Amiga OS and later in IBMâs OS/2 but it existed before those on various IBM operating systems for mainframes and minicomputers.
Now that you've previewed a sample session and the program's report output, here is the REXX program source code. Use this code to further your understanding of how REXX works in an MVS TSO environment. Be forewarned that you use this code at your own risk and I make no guarantees that it will work on your system.
