Read a table from a spreadsheet containing data on electric power outages. The table has text variables showing the region and cause for each power outage, datetime variables showing the outage and restoration times, and numeric variables showing the power loss and number of customers affected. The reason for this issue is because in some data files the variable has actual values and for some parts of the files, the data appears as an NaN. Any help would be appreciated. Theme. Copy. FileID = dir ('*.dat'); T = table; for j=1:length (FileID) opts = detectImportOptions (FileID (j).name);

Variables in T may be N-D, but all must have the same size in dimensions higher than 2. A is N-D in this case. NOTE: TABLE2ARRAY horizontally concatenates the variables in T to create A. If the variables in T are cell arrays, TABLE2ARRAY does not concatenate their contents -- A is in this case a cell array, equivalent to TABLE2CELL(T).A = table2array (T) converts the table or timetable, T, to a homogeneous array, A. The variables in T become columns in A. The output A does not include the table properties in T.Properties. If T is a table with row names, then A does not include the row names. If T is a timetable, then A does not include the row times.

I tried to use table2array to turn the table with separate columns. However, matlab did not allow me to do so. I need to turn them into columns as I want to use the retime function to do daily average calculation afterwards. But before using retime function, I will need to be able to produce a timetable with the variables in each column in it.Mar 20, 2018 · Unexpected behaviour of table2array. Documentation for table2array says, "table2array creates a homogeneous array, A, of the dominant data type. For example, if T contains double and single numeric data, table2array (T) returns an array with data type single." That surprises me. I would expect double to dominate single.

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. Tables consist of rows and column-oriented variables.

Example #1. In this example, we will create a table in MATLAB by reading the data from an in-built text file using the readtable function. Below are the steps to be followed: Initialize the function readtable with the file to be read as an input argument. For this example, we will use the in-built text file called ‘grades.txt.’.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.

If T is a timetable, then A does not include the row times.To convert, use str2num. Note that Matlab operates on doubles by default and you will get double. 3D arrays are indeed possible - for example zeros (10,10,3) will create 10x10x3 array of zeros (of double type). Thanks. If my table is "z" then ischar (z (1,9)), for one of the offending cells, returns 0 rather than 1.Convert T to a structure array. S = table2struct (T) S= 5×1 struct array with fields: Smoker Age BloodPressure. The structure is 5-by-1, corresponding to the five rows of the table, T. The three fields of S correspond to the three variables from T. Display the field data for the first element of S.YourArray = table2array(YourTable); YourNewTable = array2table(YourArray.'); YourNewTable.Properties.RowNames = YourTable.Properties.VariableNames; You can also try rot90(YourTable) and see what happens, but I'm not sure it does the same (I think it is one of those misleading names)
