Hi everyone,

Could I get some help on this, I have a large data set of a random set of data, 100x7 in a identity called v, I want to find all the numbers which are equal to or less than 2 in this set, but i dont want it to outut the value of these numbers, but to output the row on which those values are found on. At the moment i get answers ranging between 1-700 using the find function within matlab. Where I want the outputs to only be ranging from 1-100, as there is in essence 100 rows that these values can be found.

In short I want to find a program which outputs the row number which numbers only suiting my conditions lie on, as opposed to the position they fall in, for a data set of 700 numbers. Preferably I want the function to include a loop/if condition if possible

Many thanks,

Ethan

Don't edit away your question, that is extremely rude.

If you supply 2 outputs to find, it will return the row and column indices corresponding to each true element:

[rowidx, colidx] = find(data < 2);
