B = A(end,:) B =1×34 9 2 Tips Classes can overload theendfunction to implement specialized behavior. For more information, seeOverload end for Classes. If an arrayXalready exists, you can useendto grow the array size and append other elements to the array. For example,X(end+1) ...
Lets say I have a cell array C, with 1 column of different sized sub arrays (Example below) C = {1x3 Cell}; {1x5 Cell}; {1x6 Cell}; Now lets say I have a new Cell F, and I want to append it to the end of Cell Array C. ...

function output = fact(n) % FACT Calculate factorial of a given positive integer. output = 1; for i = 1:n, output = output*i; end 其中fact是函数名,n是输入引数,output是输出引数,而i则是此函数用到的暂时变数。要使用此函数,直接键入函数名及适当输入引数值即可: y = fact(5) y = 120 ...

I got it to work until i equals the length of vec and then it says the 'Index exceeds the number of array elements.' I know what the issue is but I do not know how to code around it. I have also provided some test codes. 테마복사 % Test Codes...
