I have a list of 1000000 sets of data in a .mat file. it has 5 columns, say A,B,C, Current and voltage. for many sets of data we would be having same current and voltages values. I need to read the file and then I need to filter out and get the values of current and voltage as output based on some condition. How do i do it ? I'm new to matlab. kindly help
The data looks something like this
A B C current voltage
.1 0.33 .99 1 1
0.2 0.34 .100 1 2
0.3 0.35 .101 1 3
0.4 0.36 .102 1 1
0.5 0.37 .103 2 3
0.6 0.38 .104 2 6
0.7 0.39 .105 2 8
0.8 0.40 .106 3 3
0.9 0.41 .107 3.5 3
0.10 0.42 .108 3 3.5
0.11 0.43 .109 3 0
0.12 0.44 .110 3 3.5
0.13 0.45 .111 3.5 0
0.14 0.46 .112 3.5 6
0.15 0.47 .113 3.5 7
How do i print the values of current and voltage by reading each data based on some condition ( condition is not related to current or voltage ) .The condition is with respect to time, and not A,B, C
PS: reading the file is done, I'm getting the proper output. only filtering part is left

Suppose you have two linear arrays named current and voltage, you can filter them based on a condition as follow.
It filters all values where current is greater than voltage.
