mxGetNumberOfDimensionsreturns the number of dimensions in the specifiedmxArray. The returned value is always2or greater. To determine how many elements are in each dimension, callmxGetDimensions. Input Arguments expand all Examples To open an example, type: ...
A =1x1x3 cell arrayA(:,:,1) = {'cell_1'} A(:,:,2) = {'cell_2'} A(:,:,3) = {'cell_3'} Find the number of dimensions of the cell array. ndims(A) ans = 3 The result is3because the cell array has a size of 1-by-1-by-3. ...
void*mxGetData(constmxArray* array_ptr)/* 函数功能: 得到非double型数值阵列的数据指针,double型数值阵列的数据指针用mxGetPr和mxGetPi得到。 */ 返回 mxGetDimensions 返回 mxGetElementSize 返回 mxGetEps 返回 mxGetField 返回 mxGetFieldByNumber 返回 mxGetFieldNameByNumber 返回 mxGetFieldNumber 返回 mxGe...
函数mxGetNumberOfDimensions和mxGetDimensions一般是一起使用的，前者返回输入阵列维度。若输入为2*3数组，返回2.若输入2*3*4数组，返回3.至于上面说的“这个数总是不小于2”不知道为什么，实际情况并非如此。后者返回的就是各个维度大小啦，返回值为指针变量。若输入为2*3*4，那么返回指针指向2 即几...

访问cell array >> A(1, 1) ans = 1×1 cell 数组 {3×3 double} >> A{1, 1} ans = 1 4 3 0 5 8 7 2 9 >> A{1, 1}(1, 1) ans = 1cell和struct可以相互转换。 如何将matrix转换为cell。 使用num2cell和mat2cell: >> a = magic(3) a = 8 1 6 3 5 7 4 9 2 >> b ...
Beyond the second dimension, zeros ignores trailing dimensions with a size of 1. For example, zeros([3 1 1 1]) produces a 3-by-1 vector of zeros. Example: sz = [2 3 4] creates a 2-by-3-by-4 array. Data Types: double | single | int8 | int16 | int32 | int64 | uint8 ...
Permute array dimensions. B = permute(A,ORDER) rearranges the dimensions of A so that they are in the order specified by the vector ORDER. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 ...
