如何修改该"make-matrix"?功能? [英] How to modify this "make-matrix" function?

问题描述

嗯，有缺陷的功能如下:

Well, the flawed function is as follows:

(defun make-matrix (n)
  (make-array (n n) :initial-element 0))

我想使用像(make-matrix 8)这样的函数来替换更长的(make-array '(8 8) :initial-element 0)，但是CLISP说(n n)中存在错误，因为n不是已定义的函数.如何编写此make-matrix函数?

I want to use functions like (make-matrix 8) to replace the longer (make-array '(8 8) :initial-element 0), but CLISP says there is a fault in (n n), because n is not a defined function. How do I write this make-matrix function?

推荐答案

您尝试使用(n n)，但这是Lisp语法，用于使用参数n调用名为n的函数.您应该像这样调用make-array:

You try to use (n n), but that is Lisp syntax for calling a function named n with an argument n. You should invoke make-array like this:

(make-array (list n n) :initial-element 0)
