August 22, 2021

Use uniquetol to find unique floating-point numbers using a tolerance. Put more plainly in this case the solution works since all the entries are the same size.

Please specify this or better yet provide code that creates sample data to get better answers.

Matlab unique table rows. To find unique rows in tables or timetables with respect to a subset of variables you can use column subscripting. Each element of m is the greatest. B m n unique also returns index vectors m and n such that b A m and A b n.

Below are the functions in MATLAB. It has removed the repeated instances of the row 012 because this row occurs twice in the matrix A but the two rows which consist of repeated values are still in the output. If the variable names are different you can directly assign new rows in a table to rows from another table.

Use uniquetol to find unique floating-point numbers using a tolerance. This can probably be answered with some combination of uniqueArows and accumarray. B unique A returns the same values as in A but with no repetitions.

----- Make it unique second loop. I have the following table T and I would like to keep only the rows that are unique based on the combination of the variables Ta Tb Tc and Td and where Te 2 and where Tf 3. Generate another cell array containing same cells but converted to string STR.

The resulting vector is sorted in ascending order. This is because under-the-hood the unique function for tables uses the unique function for cell arrays. The solution above works since the contents concatenate into a hyperrectangle.

Table variable names that were not valid MATLAB identifiers have been modified. The desired output is well desired_output. For example you can use uniqueAvars where vars is a positive integer a vector of positive integers a variable name a cell array of variable names or a logical vector.

A can be a cell array of strings. B unique A rows returns the unique rows of A. Dev-iL Jul 21 16 at 751.

After you import this data into MATLAB how does it appear. To find unique rows in tables or timetables with respect to a subset of variables you can use column subscripting. The unique help actually gives a different syntax.

To use the original row names as new variable names set PreserveVariableNames to true. To find unique rows in tables or timetables with respect to a subset of variables you can use column subscripting. Also the unique function will sort the output array.

For example you can use uniqueAvars where vars is a positive integer a vector of positive integers a variable name a cell array of variable names or a logical vector. The table Tnew has 104 rows. Unique Function will result in all unique rows of C if C is a table.

Find unique rows rows. If A is a table or timetable then unique returns the unique rows in A in sorted order. Generate the associated matrix with the unique indices and sort rows IC.

The unique function for the table class in MATLAB R2014a does not support columns that contain cell arrays that are not cell arrays of strings. For timetables unique takes row times and row values into account when determining whether rows are unique and sorts the output timetable C by row times. How would I do that.

A more general solution can be found at my FEX submission. This is the correct and documented behavior of unique. For example you can use uniqueAvars where vars is a positive integer a vector of positive integers a variable name a cell array of variable names or a logical vector.

Since table variable names must be unique any table variable names that happened to match the new identifiers also have been modified. The unique help actually gives a different syntax. For example Tend1end4 T2.

For example you can use uniqueAvars where vars is a positive integer a vector of positive integers a variable name a cell array of variable names or a logical vector. Elapsed time is 14218691 seconds. Add Rows from Cell Array.

U unique c This function will result in an array of unique values if the input array has some repeated values in it. In order to vertically concatenate two tables both tables must have the same number of variables with the same variable names. To find unique rows in tables or timetables with respect to a subset of variables you can use column subscripting.

Unique Functions in MATLAB. Find the index of all unique elements there id.
