In analyzing the compilation of PL/I program, the description "creation of more optimal matrix" is associated with

“compilation” refers to the process of translating the PL/I source code into machine code or another lower-level language that can be executed by the computer. This process involves several stages, including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. During lexical analysis, the compiler breaks the source code into a sequence of tokens, such as keywords, identifiers, literals, and operators. The syntax analysis phase then checks whether the token sequence conforms to the grammar rules of the PL/I language. If any syntax errors are found, the compiler will generate error messages.
