matlab code for parallel to serial converter

[abdullah gill]

function y=abc(x)
[r,c]=size(x);
a=[-1:c-2];
f=zeros(1,r*c);
for i=1:c
forj=1:r
f(i+j+a(i))=x(r,c-(i-1));
end
end

Try this Abdullah,

Assuming your Parallel stream of data is stored in a variable ParStream, then you can convert it into a serial stream as,

SerStream = reshape(ParStream,1,[])

thanks for the help but the problem is i have to use the code in system generator block so i cant use the inbuilt commands of matlab........can u help me in system generator

thanks for the help but the problem is i have to use the code in system generator block so i cant use the inbuilt commands of matlab........can u help me in system generator

this is a very useful notation for me, it will help me in the nearest future. May be in the future i will use the FPGA board but for now, may be i can help in matlab, tell me with a numerical example how you want to convert?
for example:

Reshape a 3-by-4 matrix into a 2-by-6 matrix.

A =
1 4 7 10
2 5 8 11
3 6 9 12

B = reshape(A,2,6)

B =
1 3 5 7 9 11
2 4 6 8 10 12
B = reshape(A,2,[])

B =
1 3 5 7 9 11
2 4 6 8 10 12


or do you want your serial data (one dimension) to be in parallel (rows)?

tell me

thanks

Added after 43 minutes:

any way: i did this code for you:

%% parallel to serial
clc;
clear all;
close all;

a=[1 2 3 4;5 6 7 8;9 10 11 12;13 14 15 16;17 18 19 20]
r=length(a,1))
aser=[];
for l=1:r
aser=[aser,a(l,];
end
aser


results:::::::

a =

1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
17 18 19 20


r =

5


aser =

Columns 1 through 14

1 2 3 4 5 6 7 8 9 10 11 12 13 14

Columns 15 through 20

15 16 17 18 19 20
