i have matrix in the form of .csv nchoosek can take the .csv file as input....?

[KSSV]

Load the data into MATLAB workspace using csvread or xlsread or readtable and use nchoosek

[msr16]

v= csvread('file name')

c= nchoosek(v, 4)

i use this to find permutation but it shows the error.

This i my csv file(TSP10.csv)

im stuck here please help me to find the permutation of matrix in csv file.

[KSSV]

A = csvread('TSP10.csv') ;
c= nchoosek(A(:), 4)

1423

1432

2143

Your result should not be 24 x 4!!

24 x 4 would be for permuting 4 entries, but you have 16 entries.
