i have a code for performing ebcot compression..I have to perform for low,high,vertical,diagonal coefficient

[out,mat_log]=ebcotcomp(A,bx,by)

[out,mat_log]=ebcotcomp(H,bx,by)

[out,mat_log]=ebcotcomp(V,bx,by)

[out,mat_log]=ebcotcomp(D,bx,by)

A-low pass filter

H-high pass filter

V-vertical

if i run this code ,I get an error

Error in ==> er at

[out,mat_log]=ebcotcomp(A,bx,by)

but,if i comment first line and run,i get the result for other three,if i do not comment i get this error.....

please suggest some idea

so what does the error say exactly?

%%

try

[out,mat_log]=ebcotcomp(A,bx,by)

catch e

disp('error');

e.message

end

do you also get the error if you swap the two first lines? is it still at the first line? or always where A is?

only where A is
