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.
REXX Talks REXX Programmers Shouldn't Overlook 'Stacks' Schedule Tasks Using Cron and REXX REXX Routines for Easy Updates or Generating Workload Leveraging SMF Data With (or Without) REXX REXX Offers Tools for Automated Processing of SMF Data Processing SMF Records Using REXX A Closer Look at the REXX Code for Processing SMF Data In this series of articles, Iâll provide a beginnerâs guide to the REXX* programming language on z/OS*. Letâs head straight into reading and writing files. Getting Started. Reading z/OS data sets in REXX requires two steps. First, allocate the data setâthis is a Time Sharing Option (TSO) command. Second, process the records in the data setâthis is implemented as a TSO REXX command.
