5. 数据返回类型 从 数据库中读取数据到matlab有三种数据类型(默认为元胞类型cellarray),分别为元胞类型(cellarray),数字型 (numeric),结构型(structure)。可以在链接数据库之前通过setdbprefs函数来进行设置。如果数据库文件中全部是数值型数据时 最好采用numeric型的数据,这样可以使得读取速度大幅提高,特别是在大型...

Assuming this is your cell array structure, the‘Pts_Status_1’array will return the correct patient information: patients = {'patient''status''genotype''genotype' [ 1] [ 1]'A''C' [ 1] [ 1]'E''F' [ 2] [ 1]'B''D'
这是一个2×2的cell array,现在我要将它变成一个1×4的array,具体操作见下图 图7-13 1×4array 可以看到,reshape函数里面带三个参数,第一个是需要转换的矩阵的名字,第二个是需要转换的行数,第三个是需要转换的列数 八、file access 我们有时候需要把计算完的workspace里的data存储为档案,或者是将存储的档案...
I need to access the cell array of all the variables in the base workspace from inside a GUI function and I can not use the "who" command because it returns the variables defined inside the GUI function not the main workspace. And is there any for using "...
C = 3x2 cell array {'2023-07-23'} {[10 20 30 40]} {'2023-07-24'} {[11 22 33 44]} {'2023-07-25'} {[ 1 2 3 4]} >> So we now have 3 rows and 2 columns making it a 3x2 cell array.Now to access the first row you can simply do as follows −C(1,:) ...
