As the name also implies, the data in G2:J14 is expected to be text with length > 0. The fields in the listbox are populated with data that is read from a CSV file. If you need to first generate all combinations of 16 rows out of 559 and then discard the ones with non-unique columns, you would need to loop through 3e30 elements , for reference matlab loops through 3e8 elements in about a As we know that for sorting the numeric expressions and functions in Matlab we used the Matlab sort function. Select a blank cell besides the columns you will count unique rows, says Cell E2, type Source. I have table_1 and say it has 6 columns. The first column would be all unique date, then there would be columns for every unique days in the table B, containing the value of volatility and NaN if there was no such combination.

I am working on a program that has a GUI, and contains a listbox. The flag 'rows' tests rows uniqueness (taking all columns into account). unique Find unique elements of vector Syntax b = unique(A) b = unique(A, 'rows') [b, m, n] = unique(...) Description b = unique(A) returns the same values as in A but with no repetitions. The lines for data Y1, Y2,…,Yn with respect to their corresponding set of data X1, X2,.., Xn logInd = Columns 1 through 13 1 0 1 0 0 0 0 0 0 0 0 0 0 Columns 14 through 20 1 0 0 0 0 0 1 MATLAB returns an array that matches the elements of the array X , element-by-element holding 1s where the matching values in X are the desired values, and 0s otherwise. I would to love to have a code that will enable me to get data from a specific column(s) by using the column number or numbers.So lets say I want data from columns 2 and 3, the code should enable me to enter 2 and 3 and then it will search the table and return the data associated with the specified column(s).

The input to this function needs to be one-dimensional, so multiple columns will need to be combined. I was preparing some results of an image segmentation algorithm for publishing and needed a way to find all pixels that match a variable set of multiple numbers (e.g. In MATLAB, I can do something like size(b,2) To get the number of unique columns. This MATLAB function returns a copy of the dataset A that contains only the sorted unique observations. [Since there are 3 duplicates for the pair 4,5 and 2 duplicates for the pair 2,6.] 1. [C,ia,ic] = unique(A) also returns index vectors ia and ic such that C = A(ia,:) and A = C(ic,:). In both orientation, legend gets too big to display. pd.unique returns the unique values from an input array, or DataFrame column or index.
