16 Σεπ 2014 · In MATLAB, first convert the @table object into a struct, and retrieve the column names using: table_struct = struct(table_object); table_columns = table_struct.varDim.labels; save table_as_struct table_struct table_columns; And then you can try the following code in python:
If you would have used MATLAB’s & or | operators, you should use the NumPy ufuncs logical_and / logical_or. The notable differences between MATLAB’s and NumPy’s & and | operators are: Non-logical {0,1} inputs: NumPy’s output is the bitwise AND of the inputs. MATLAB treats any non-zero value as 1 and returns the logical AND.
19 Νοε 2015 · You can add a new table variable by using either dot notation or the "addvars" function. Dot notation adds new variables to the end of table. If you use the "addvars" function, then you can choose the location of the new table variable. For example, this code creates a table and two column vectors.
For example, to add a column vector named A after the last variable in T1, use T2 = addvars(T1,A). example T2 = addvars( T1 , var1,...,varN ,'After', location ) inserts the variables to the right of the table variable indicated by location .
T = table (); Add a first column to it using one of the following two syntaxes (or others as needed): T.ONE = NaN; %Or T.ONE = ""; The first is for a numbers column type, and the second for a strings type (others may work as well). Now, lets make it have 2 rows for the demonstration: T = [T; T] begetting: T =.
23 Μαρ 2016 · You can create NaN values using the nan() function, then append them to your table as new data. You'd need the new data to be a table with the same variable names. I am assuming here that all of them are numeric. In your case. T=[T; array2table(nan(3,8),'variablenames',T.Properties.VariableNames)];
