老旧软件之Matlab1

翻一块大学时候的旧硬盘发现的。应该是上大学时从某个国外竞赛网站下面拖下来的。

dosbox跑了下,能跑起来。不过已经忘记语法了。

ABSTRACT. MATLAB is an interactive computer program
that serves as a convenient "laboratory" for
computations involving matrices. It provides easy
access to matrix software developed by the LINPACK and
EISPACK projects. The program is written in Fortran
and is designed to be readily installed under any
operating system which permits interactive execution of
Fortran programs.
