The plain parse-tree constructed in that phase is generally of no use for a compiler, as it does not carry any information of how to evaluate the tree. WebSep 24, 2024 · Answers (3) No, Matlab is not a "compiler", but an "interpreter". A compiler converts the source code to an executable file, which is not readable by human anymore. When working with an interpreter, the readable source code remains the base of what is executed. But even in Matlab the code is interpreted and optimized, here by the "JIT …
