When I use readcell() to import a .xlsx file, any empty cells are stored as 1x1 missing. Then if I try to write the cell array back to a .csv file using writecell(), I get an error that missing values aren't allowed. It seems strange to me that readcell() would create ...

元胞数组(cell array)是一种具有容器特性的数据类型,每个元素可以包含任何类型的数据 4.说明 元胞数组创建和扩展时默认填充元素是空矩阵[] 元胞数组不需要完全连续的内存,但每个元素需要连续的内存 对大型的元胞数组,增加元素数量可能导致Out of Memory错误 因此,必要时,元胞数组需要初始化和预分配内存 5.实例演示...
exact same format or contents as the original data. If you need to save your cell array and retrieve it at a later time to exactly match the original cell array, with the same data and organization, then save it as a MAT-file.writecellwrites an inexact table in the following instances...

cellNum=(size(rawData,2)-1)/3; 原始数据是table类型,需要先转成array,double类型,方便后续计算。 如果有些时间点的数据丢失,可以检测NAN,并把这一数据删除。 tmpCellPos=table2array(rawData(:,ii*3:ii*3+1));tmpCellPos(any(isnan(tmpCellPos),2),:)=[];% in case there is missing data ...
fmincon函数应用四种不同的算法:内点法(interior point);序列二次规划算法(SQP);有效集法(active set);信赖域有效算法(trust region reflective)。 如果采用SQP算法可以设置 OPTIONS = optimoptions('fmincon','Algorithm','sqp'),再把OPTIONS赋给fmincon
