maxk() was introduced in 2017b so if you are using version prior to it use:

1) sort() row wise in descending order.

2) Just extract the first three columns from it.

When i use sortrows command all the rows are getting sorted.

what i need is i need to sort the numbers present in each row but not sorting the order of rows.

Could you please help me on this.

You have some problems in reading , read my answer once again THERE WAS NO SORTROWS() function mentioned there!!
