say I have an array that I want to run a function over each of its elements, I could easily do this with arrayfun(@f,v) where f is my function name and v is my vector. But now say f is defined to take two input arguments, that is f(e,k) where e is an element of the...

I have the following problem: I have a function such as: fun = @(x1,x2)100*(x2-x1^2)^2+(1-x1)^2 However, I need to convert this to the form: fun = @(x)100*(x(2)-x(1)^2)^2+(1-x(1))^2 so that I can use it as the objective function for fmincon. ...

3-D implicit function to plot, specified as a function handle to a named or anonymous function. Specify a function of the form w = f(x,y,z). The function must accept three 3-D array input arguments and return a 3-D array output argument of the same size. Use array operators instead...
用过Matlab的人都知道,Matlab是一种解释性语言,存在计算速度慢的问题,为了提高程序的运行效率,matlab提供了多种实用工具及编码技巧。 1. 循环矢量化 Matlab是为矢量和矩阵操作而设计的,因此,可以通过矢量化方法加速M文件的运行。矢量化是指将for循环和while循环转换为等价的矢量或矩阵操作。下面给出一个循环的例子:...
