i have a mistake named Subscripted assignment dimension mismatch.

krillbest=zeros(3,16,q1-1,cn);  
for i=1:q1-1       
 krillbest(:,:,i,1)=bestkrill(:,:,i);  
end

please return me immmediately, i have to solve this problem immediately.Thanks for everything

What is size(bestkrill) ?

[fatma]

bestkrill and krillbest are the 3 rows and 16 columns.they have the same size

[fatma]

i only want that for the bestkrill 1. must be krillbest(3,16,1,1),i want bestkrill 2 must be krillbest(3,16,2,1),it must be go on till q1-1,thats all,i am still suprised for seeing this mistake, because they are the same size both column and rows

Answer 1

[Walter Roberson]

krillbest=zeros(3,16,q1-1,cn);  
krillbest(:,:,:,1) = bestkrill;

If you want bestkrill copied to each of the cn layers then use

krillbest = repmat(bestkrill, 1, 1, 1, cn);

Illustration:

q1 = 11;
cn = 5;
bestkrill = rand(3,16,q1-1);   %put any data you want here.

krillbest=zeros(3,16,q1-1,cn);  
for i=1:q1-1       
  krillbest(:,:,i,1)=bestkrill(:,:,i);  
end

The code from krillbest onwards was copied exactly from your posting, and it works without problem, provided that the size() of the first two dimensions of bestkrill are the same as 3, 16, and that the size of the third dimension of bestkrill is at least as large as q1-1 .

It seems likely to me that in your code, bestkrill is not the size you expect. You need to look at size(bestkrill) and be sure that really does start 3, 16.

At the command line, give the command

dbstop if error

and then run your initial code. When it stops with the error, examine the size() of each of the variables.

[fatma]

they are constant,and 3x16 matrices,i dont know the meaning of dbstop if error .whats that?

[fatma]

there is still the same mistake, i still could not find a solution for it

Answer 3

[fatma]

dbstop if error i have never used,because i am beginner in matlab,thats all sorry for my illiteracy,

best krill is this val(:,:,1) =

[fatma]

i have no problem the size of best krill,they are constant, i try to optimize the standart image .thats all

[fatma]

now i solve the problem,thank you for everything

[Star Strider]

We are happy for you.
