Delete Cells The syntax for removing rows or columns of a cell array is consistent with other MATLAB arrays. Set the cells equal to a pair of empty square brackets. For instance, remove the second row ofC. C(2,:) = [] C=2×4 cell array{'one' } {[ 2]} {0x0 double} {0x0 do...
1.1.6 细胞数组(Cell Array)和结构体(Structure) 1.细胞数组 在处理函数返回值和示波器部件输出时,常常会遇到不同维度的返回值同时被一个函数返回的情况。同时,通常也希望能使函数的输入参数尽可能少。MATLAB提供了允许这样做的方式。 细胞数组是MATLAB特有的一种数据结构,它的各个元素可以是不同的数据类型。细胞数...

% The return value A is an array containing the image data. If the file % contains a grayscale image, A is an M-by-N array. If the file contains % a truecolor image, A is an M-by-N-by-3 array. For TIFF files containing ...
If the name of a variable is a value of ItemType, then calling clear followed by that name deletes the variable with that name. clear does not interpret the name as a keyword in this context. For example, if the workspace contains variables a, all, b, and ball, clear all removes the...
