function [out1,out2] = humps(x) HUMPS A function used by QUADDEMO, ZERODEMO and FPLOTDEMO. Y = HUMPS(X) is a function with strong maxima near x = .3 and x = .9. [X,Y] = HUMPS(X) also returns X. With no input arguments, HUMPS uses X = 0:.05:1. Example: plot(humps) See QUADDEMO, ZERODEMO and FPLOTDEMO.

这代码的作用是根据输入参数的个数来变量`fuzzy`的值，并计算变量num_train`和`num_test`的值。首先，`nargin<7`判断输入参数的个数是否小于7。如果是，没有传入第7个，将变量`fuzzy`设置为`true`。接着，使用`size(data,1)`计算变量`data`的行数，并将结果赋给变量`num_train`。使用`size(test,1)`计算变量`test`的行数，并将结果赋给变量`num_test`。最终，变量`fuzzy`的值取决于输入参数的个数，而变量`num_train`和`num_test`的值分别表示变量`data`和`test`的行数。
