Using a single subscript to refer to a particular element in an array is calledlinear indexing. If you try to refer to elements outside an array on the right side of an assignment statement, MATLAB throws an error. test = A(4,5) ...
While linear indexing can be less intuitive visually, it can be powerful for performing certain computations that are not dependent on the size or shape of the array. For example, you can easily sum all of the elements of A without having to provide a second argument to the sum function. ...
1、Row vector(行向量):a=[1 2 3 4] 2、Colunmn vector(列向量):b=[1;2;3;4] 注意:a*b(inner product内积);b*a(outer product外积) 练习:在matlab中输入以下矩阵3 答案:A=[1 21 6 ; 5 17 9 ; 31 2 7] 七、Array Indexing(数组索引) 1、Select a certain subset of element inside a ...

在第三章中,我们介绍了如何使用中括号[]来创建普通的数值数组。创建元胞数组(cell array)则需要使用英文输入模式下的大括号{}(又称花括号)。在元胞数组中,同行元素之间可以用逗号或空格分隔,而行与行之间则通过分号或回车键分隔。 我们可以在元胞数组中放入任何类型的数据,例如: ...
C=2×3 cell array {[ 1]} {[ 2]} {[ 3]} {'text'} {5x10x2 double} {3x1 cell} You also can use {} to create an empty 0-by-0 cell array. C = {} C = 0x0 empty cell array To create a cell array with a specified size, use the cell function, described below. You...

If v is nx2 array idx=sub2ind(size(A),v(:,1),v(:,2)) A(idx) Jori2015년 8월 7일 편집:Jori2015년 8월 7일 MATLAB Online에서 열기 The size of v is 1 x N. I do not know N beforehand. Using idx = sub2ind(size(A),v) does not work. So I would need...
Using Test Case 2 input signal values, the ComputeIndex MATLAB Function block determines the range of array indices to be 1:4. One-based indexing is consistent with MATLAB syntax, so these indices are valid for the ArrayOp_Matlab MATLAB Function block and the ArrayOp_MAL Stateflow® chart...
Function_Filename 是函数所对应的M文件的名称或MATLAB内部函数的名称 @是句柄创建操作符 Function_Filename 变量保存了函数句柄,并在后续的运算中作为数据流进行传递 调用 通过函数句柄调用函数,需指定函数的输入参数, Function_Handle(arg1, arg2, ... , argn) ...
