hello, I have a 3D matrix array of 1x1x10001 and I want to delete the first array so I use the codingan below but I get an error like this
Unable error to delete elements from this array because dimension 3 has fixed size.
if anyone can help me how to solve this error and I can delete the first array, thank you very much I really hope the help of good people.
function y = fcn (u)
u(:,:,1) = ;
In your function y will not be set. You only try to remove one element from the input, that's wasting time. When I run this at the command-line prompt:
q = randn(1,1,12);
q(:,:,1) = ;
everything works fine.
In the function you will have to assign something to the output variable y. Otherwise matlab will not know what to put into y, should it be exp(1) that's calculated? only the first component of u?, the sum of all components of u? Otherwise your function will return an error or a warning that y is not assigned in fcn (forgotten the exact message). This you do something like this:
function y = fcn(u)
u = randn(1,1,1001);
u(:,:,1) = ;
y = u;
