You can use table function which can accept array with named variables that can contain different data types. The example code is given below:

example. stats = grpstats (X,group) returns an array with group summary statistics for the columns of the matrix X, where the function determines the groups by the grouping variables in group. If X is a numeric or logical matrix, then the summary statistic is the mean of each group for each column of X . Otherwise, the summary statistic is the ...Create two tables. Create one table, T, with information collected from a patient questionnaire and create another table, T2, with data measured from patients. Each table has 100 rows. T = table (Age,SelfAssessedHealthStatus,Smoker); T.SelfAssessedHealthStatus = string (T.SelfAssessedHealthStatus); T2 = table (Height,Weight,Systolic,Diastolic); Pool tables are a fun accessory for your home, but they can suffer some wear and tear after years of play. Use this guide to understand some of the common issues pool table owners run into, and whether or not you can solve them yourself.

2. Because table already implements () indexing, it's not really clear to me how you would expect to index MyArray. Your example almost looks to me like MyArray = [T1, T2]. I'm not sure if it satisfies your needs, but you can have table objects with table variables, like this: T = table (T1, T2); You can then using indexing as normal, e.g.

To build block arrays by forming the tensor product of the input with an array of ones, use kron.For example, to stack the row vector A = 1:3 four times vertically, you can use B = kron(A,ones(4,1)).. To create block arrays and perform a binary operation in a single pass, use bsxfun.In some cases, bsxfun provides a simpler and more memory efficient solution.

Hello Mahmoud, There are two issues going on here. One is that to specify the column names for a table, you want to provide them as part of a name-value pair argument to table: Theme. Copy.

Things like groupsummary and varfun can ...If a variable in T1 is a table itself, then splitvars uses the names of its variables (and, if necessary, the name of that table) to make unique names for the new variables in T2. To merge variables into one multicolumn variable, use the mergevars function. example. T2 = splitvars (T1,vars) splits only the table variables specified by vars.
