使用size函数可以获取结构数组或任何结构字段的大小。给定一个结构数组名作为变量,size返回一个数组的维向量。给定array(n).field形式的变量,size函数返回一个包含字段内容大小的向量。 (7)结构数组的嵌套 一个结构字段能包含另外一个结构,甚至是另外的结构数组。一旦创建了一个结构,就可以使用struct函数或赋值语句,在...

If the input X is a multidimensional array, fft operates on the first nonsingleton dimension. Y = fft(X,n) returns the n-point DFT. fft(X) is equivalent to fft(X, n) where n is the size of X in the first nonsingleton dimension. If the length of X is less than n, X is padd...
y-coordinates, specified as a matrix the same size as Z or as a vector with length m, where [m,n] = size(Z). If you do not specify values for X and Y, mesh uses the vectors (1:n) and (1:m). You can use the meshgrid function to create the X and Y matrices. The YData...

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: 上面代码中我们创建了一个3行2列的元胞数组c1:c1的第一行第一列保存的数据是一个长度为3的...

MATLAB Functionblocks support variables that change size during simulation if theSupport variable-size arrayblock property is enabled. SeeSupport variable-size arrays. However, only variables that you specify as variable size can change in size during simulation. Depending on the scope, you can set ...
