C=3×2 cell array{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double} It is a common pattern to combine the previous two lines of code into a single line. C = cell(size(A)); Tips
writecellwrites out cell arrays that have more than two dimensions as two dimensional arrays, with the trailing dimensions collapsed. Excel convertsInfvalues to65535. MATLAB®convertsNaN,NaT,<undefined>categorical values, and<missing>string values to empty cells. ...
AI代码解释 A=num2cell(rand(1000));%for测试 tic;form=1:500forn=1:500A{m,n}=fun(A{m,n});end end tfor=toc%cellfun测试 tic;A=cellfun(@fun,A,'UniformOutput',false);tcel=toc 在小编电脑上运行结果为:tfor=0.1164;tarr=2.1745,for循环比cellfun快18倍左右(注:运行结果和电脑硬件有关)。 ...
For example, cell([2 3]) returns a 2-by-3 cell array. example D = cell(obj) converts a Java array, .NET System.String or System.Object array, or Python sequence into a MATLAB cell array.Input Arguments expand all n— Size of square cell array integer value sz1,...,szN— Sizes...
()函数或 readcell()函数 T = readtable(filename,Name,Value) 这里,filename—excel文件,文件后缀是 .txt、.dat 或 .csv(带分隔符的文本文件) .xls、.xlsb、.xlsm、.xlsx、.xltm、.xltx 或 .ods(电子表格文件) .xml(可扩展标记语言 (XML) 文件) .docx(Microsoft® Word 文档文件) .html、.xhtml ...
Data Types:cell Warnings produced while processing the header file, returned as character array. Limitations You must have a supported C compiler and Perl must be available. Do not callloadlibraryif the library is already in memory. To test this condition, calllibisloaded. ...
你自己对比一下V(i,j)=[...]; 和上一段正常的程序中seg(row,col) = {A(...)};看出问题了吧。改成V(i,j)={[...]}; 或者V{i, j} = [...]; 也是可以的。因为V(i,j)是一个cell，不能赋给它一个矩阵。M = [...]; 之所以是正确的是因为M这样就被定义成了一个矩阵。
Vector describing the distribution by rows of the input array, specified as a numeric vector. When you do not specify how to divideAalong any other dimension, themat2cellfunction returns ann-by-1 cell arrayC, wherenequals the number of elements inrowDist. ...
Syntax A = cellfun(func,C) A = cellfun(func,C1,...,Cn) A = cellfun(___,Name,Value) [A1,...,Am] = cellfun(___)Description A = cellfun(func,C) applies the function func to the contents of each cell of cell array C, one cell at a time. cellfun then concatenates the outputs...
Convert a cell array containing different data types to an ordinary array. Create a cell array that containssingleanddoublevalues. a = single([1 2 3]); b = double([2 4 6]); C = {a;b} C = 2×1 cell array {[1 2 3]} {[2 4 6]} ...
