1.5.1  查询某一命令或函数

如果你要对某一命令或函数进行查询,直接在help后跟上该命令或函数名即可,即用下列程序

        help 函数(命令)名

可得到帮助,例如

》help  feval

屏幕显示内容如下:

FEVAL Execute function specified by string.

If F is a string containing the name of a function (usually

defined by an M-file), then  FEVAL(F,x1,...,xn)  evaluates

that function at the given arguments. 

For example, F = 'foo', FEVAL(F,9.64) is the same as foo(9.64).

FEVAL is usually used inside functions which have the names of

other functions as arguments.  Examples include FZERO and EZPLOT.

 [y1,..,yn] = FEVAL(F,x1,...,xn) returns multiple output arguments.

Within methods that overload built-in functions, use

BUILTIN(FUN,...) to execute the original built-in function.

See also BUILTIN.
