Call the function with arguments that do not match the input parser scheme. Specify a nonnumeric value for thewidthinput: a = findArea('text') Error using findArea (line 14) The value of 'width' is invalid. It
Call the function using the second cell of x. Because the input argument contains cell indexing, the inputname function returns an empty char array for the first variable name and all subsequent variable names. Get getname2(x{2},y,z) Calling variable 1 is ''. Calling variable 2 is '...

这句说明你的代码里出现了一个你自己定义的函数“fuction”，但输入变量是“char”就是说未定义输入变量 Error: Function definitions are not permitted in this context.---这一句是说：定义函数是不允许这样的！函数“function

Axis label, specified as a string scalar, character vector, string array, character array, cell array, categorical array, or numeric value. Example: 'my label' Example: {'first line','second line'} Example: 123 To include numeric variables with text in a label, use the num2str function....
就是说你sqrt（）括号中S是个变量导致sqrt里的值是个变量，，而且你并没有给变量赋值，或者写成函数的形式，然后再调用，所以无法求值。
This MATLAB function declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN.
