verilog matrix
Hello, everyone
I have 64 successive channel matrix H1, H2..H64
And in my algorithm, I need to find the inverse of each matrix Hi in verilog on FPGA before esitimating the channel quality in the following
I have read some papers, like using the trace of the matrix to get the...
envelope matlab
you may do it like the following:
plot(t,y)
hold on
ind=find(diff(sign(diff(y)))==+2)+1;
val=interp1(t(ind),y(ind),t,'linear');
plot(t,val,'r')
Matlab
it is easier to write a function of your own like this:
function y=mycos(x);
y=cos(x/180*pi);
Since cos is a built-in function that you cannot change its source code, another way may be to name the function above as cos and put it in your "work" folder, generally the m file with the...
thanks very much for your reply.
It is a text file.
If I write the script myself, should the algorithm be like this?
fseek(fp,-1*buffersize,SEEK_END);
fgetpos(fp, &filepos);
while( n< number of lines){
fread(buffer, buffersize,fp);
reverse the array and calculate the existence of...
hello. everyone.
I have a large EDA report about several giga bytes,
and I need to extract some lines from the report, for example, the last 100 lines and then print these lines in an reverse order in another file.
Since for some line, it may contain about 1M byte data, it seems very...
tridiagonal matlab
hello
the first diag in your statement just generates a constant 1
which means, it just plus 1 to the sum(diag(1,-1), diag(1,1))
you may see it from the following:
diag(1)
ans =
1
?diag(1,-1)
ans =
0 0
1 0
?diag(1,1)
ans =
0 1
0...
matlab tridiagonal matrix
I think that statement is OK, if our understanding is the same
example:
diag([1,2])+diag(1,-1)+diag(2,1)
ans =
1 2
1 2
?diag([1,2,3])+diag([1,2],-1)+diag([1,2],1)
ans =
1 1 0
1 2 2
0 2 3
