Hi,
I am new to MATLAB GUI and have no idea of how to use it. Here is the image screenshot of my GUI.
What I want is that whatever is written in the text box next to secret message (in string format), it would be saved to a variable sec_info (string type) in workspace whenever the Send...
Well, what I actually want is to convert
-127 to 129
-126 to 130
-125 to 131
And so on...
@andre_teprom: Your provided equation is not doing this.
@KerimF: Yes man it worked. Thanks!
Hi,
I want to find the 2's complement of -127 in MATLAB for 8 bits. I want to find 2's complement of a. So, I multiply it by -1 and takes its dec2bin:
a=-127
a=-1*a;
b=dec2bin(a,8);
Now b = '01111111'
I want to invert all the bits of b and add 1 to it. How can I do it?
Thank you.
Hi,
I am using a code which calls Java inside the .m MATLAB files. Both the .m files are working fine. But the problem is that if I send data greater than 8192 bytes (8 KB) from server to client, like 9000 bytes, the server will send all 9000 bytes to client but the client will pick first 8192...

The port number I used is 29250.
When I select a file and send it to the receiver, a dialog box at the receiver pops up asking me to accept the incoming file.
When I click Yes to...

It is giving me some error when I run the project. The error message is also attached...
Hi,
I have a .wav file in my PC and I want to convert it to bits. I have tried the command:
[x,fs,nbits]=wavread('test.wav');
This command gives me floating point signed numbers for each sample however I need bits. What should I do in case I need actual bits and not these signed numbers...
Hello,
I am writing code for the main file of my project which makes use of other files within the same project. I am trying to call some files into my main project file with the following commands:

Hi,
I want to know how compression for voice is achieved in GSM networks? Is it performed in time-domain or frequency-domain and if someone has documentation related to GSM compression? I am looking for that.
Please help me in this regards.
Thank you.
