Now I have seen what goes on into varfun, I am not so sure that this solution will be faster.

go figure.)Дiscussion: Initially I tried to make the varfun solution work (hence the T2 name of the result), and wanted to recommend this one, because I didn't like the table/cell/table conversion of the other solution. Notice that again we had to reassign the column headers on the newly created table ( the irony is varfun choked trying to apply the function on the column headers, but does not re-use or return them in the output. This will produce the same table than in the example 1 above. For more information, see Create Tables and Assign Data to Them or watch Tables and Categorical Arrays. Each variable in a table can have a different data type and a different size with the one restriction that each variable must have the same number of rows. Tables consist of rows and column-oriented variables. T2.Properties.VariableNames = T.Properties.VariableNames table is a data type suitable for column-oriented or tabular data that is often stored as columns in a text file or in a spreadsheet. For example: cellnum2str = with that, you can now use it to convert your table: %% Use 'varfun' The trick to overcome that, is to send a customised version of num2str which will accept cell arrays. The syntax for working with a tall table is very similar to that for working with a table.

#TABLE MATLAB HOW TO#

Tall arrays and tall tables know how to read the data in one chunk at a time, perform the calculations you want, and then gather up the output at the end.

A tall table is a kind of a tall array in MATLAB. As we saw above, num2str errors when met with a cell array. That can easily be done by creating a tall table.

If you look at the varfun code at the line indicated by the error, you'll notice that internally, data in your table are converted to cell arrays and the function is applied to that. You'd think that a simple T2 = varfun(, T ) Use the fprintf function in Matlab to make your table printout look good. Varfun is for Tables the equivalent of cellfun for cell arrays. Printing a table in Matlab doesn't always mean that your table is going to look good in printed form.

These method is suitable for relatively small tables, as the round trip table/cellarray/table plus the call to cellfun will probably be quite slow for larger tables. Notice that we had to recreate the column names (copied from the initial table), as these are not transferred into the cell array during conversion. Produces a new table containing only strings. This section lists all of the valid keys that a table struct can contain. T3.Properties.VariableNames = T.Properties.VariableNames MATLAB Figure Reference: table Traces A table trace is a struct inside fig.data which has type equal to 'table'. T3 = cell2table( cellfun(, table2cell(T), 'uni',0) ) I recreated a table with the same data than in your example. There are 2 possible way to work around that to convert all your values to character arrays: num2str() is also valid), but it will bomb out if you try to throw a cell array at it (even if all your cells are numeric). The fprintf() function is used to display formatted text and variables in MATLAB. Print Table Using the fprintf() Function in MATLAB. However, it can deal with purely numeric arrays (e.g. In this tutorial, we will discuss how to print a table using the fprintf() function in MATLAB. Add the first names of the patients as table variables.Yes, num2str accept a single variable of any type and will return a string, so all these operations are valid: > num2str('123') Specify the last names of patients as the row names of the tables. A table can have row names along its first dimension, labeling the rows, but is not required to have them. An inner join keeps only those table rows that match with respect to the key variables.Д¬reate two tables of patient data. When you join tables or timetable together using the join, innerjoin, and outerjoin functions, you can specify row labels as key variables.ДЇor example, you can perform an inner join two tables together, using row names and a table variable together as key variables. When you group rows together using the rowfun, varfun, stack, and unstack functions, you can specify row labels as grouping variables. Use Row Labels as Grouping or Key Variables
