I get the data as a cell array, with each cell having a column of data. What I've done is cast everything into a string and take the transpose of the data (it seems MATLAB does things in a column-major order). Also note I've added a bunch of commas without data inbetween. That...

2. Define the inputs and outputs 输入变量:当输入字符型“reset”用于已输入数N、sum(xi)、sum(xi^2)的清零 the algorithm(伪代码) 这个函数分为4步: 1)check for a legal number of arguments 2)check for a 'reset',and resets sums if preset,otherwise,add current value to running sums ...

单元格数组-单元格数组(cell array)能够存储不同大小和类型的数据。例如,cellArray = {1, 'hello', [1, 2, 3]};。 表格-用于存储列形式的数据,每列可以是不同的类型。例如,tableVar = table([1;2;3], ['M';'F';'M'], 'VariableNames', {'Age','Gender'})。
