I'm quite new to Common Lisp, and I've come across a problem when trying to use the package Matlisp, which I load with (ql:quickload :matlisp).
When I try to use the package, for example, by simply executing:
我总是收到一个错误，说：
When I try to use the package, for example, by simply executing:
(randn '(2 2))
我总是收到一个错误，说：
“不会（没错，你读对了，小子！）为抽象张量类“TENSOR DOUBLE-FLOAT STRIDE-ACCESSOR SIMPLE-ARRAY”生成方法。” [类型为TENSOR-ABSTRACT-CLASS的条件]
在回溯中，我看到许多“打印对象错误”消息（如附图所示）。
我尝试过的所有matlisp函数都出现了这个问题。我可能缺少非常基本的东西，还是这可能是包的问题？
我在Emacs 25.0.50上运行slime，我的Lisp实现是SBCL 1.2.11，这些信息是否相关。
任何帮助都将不胜感激！
以下是回溯：
