Compiler Mini Matlab

Author: Ng Zheng Jue, Heng Chia Ying, Lim Yi Jing, Ong Ming Jie, Ng Rui Qi, Tan Hong Guan

   Compilers are essential software tools that bridge the gap between high-level programming languages and the low-level machine code executed by computers. They play a crucial role in translating human-readable code into efficient and executable instructions. Given the assignment of developing a compiler, our team has developed a compiler that can perform the same functions as a Matlab software. We have implemented some of the exact same functions from Matlab. Through developing this software, we hope to be able to create a software that is like Matlab and add even more functions into it, being able to easily customize it.

Wrong format of operation:

No	Wrong	Output	Correct
1	sin30	Undeclared Identifier !	sin(30)
2	tranpose([1 2 3])	The identifier is not a function	transpose([1 2 3])
3	mod([1 2; 3 4])	The arguments number are too few, 1. Use 2 arguments.	mod([1 2; 3 4], 3)
