First of all your data needs to have 2^n samples for FFT... you have provided 15, so i have added 1 more to make it 16.
The main thing you were missing was "FFTSHIFT()"
try the following code and see the attached pic for results.
clear all; close all; clc;
A=[0.000010 0.115949
0.000020...
No. Basically what I'm saying is that if its not marked, you will not know just by looking at it.

ecaps = electrolytic caps?
electrolytic capacitors are usually marked. If they look like ceramic capacitors, then it hard to tell of coarse.
Usually, Tantalum caps are the ones that look similar to ceramics... but alot of them are marked. If they are not marked, then it will be hard
this means you are using a complex fft.... if you want an even fft output, you need to make sure that you have real inputs.
can you post:
1. your complete input
2. matlab commands you are using
3. output data
or a screenshot
I have an RF UART module device which is sleeping (slave device). I can wake it via a timer and force it connect to any available wireless (master) devices nearby. However, I am wasting slave battery this way. Is there any wireless module that can sleep and I can wake it up wirelessly on demand...
