Putting Consecutive numbers into variables

1 次查看(过去 30 天)
I data in this format a=[1;2;3;7;0;6;7;8;9;2;4;3;14;15;16;17;0;9;2];
what I need to accomplish is to put consecutive numbers into different variables...
in this case the expected outcome is a1=[1;2;3]; a2=[6;7;8;9]; a3=[14;15;16;17]; How do I

Do NOT do this. Dynamically accessing variable names is one way that beginners force thmeselves into writing slow, complex, obfuscated, buggy code that is hard to debug:
Your code will be simpler and much more efficient if you simply use one container variable (e.g. a cell array, as my answer shows).

You can access the data in the cell array C using basic indexing:

F = @(b,e)A(b:e);
Please explain what b and e mean
are they variables...I don't know how to use them for a new dataset

b and are are dummy parameter names, similar to
function result = F(b, e)
result = A(b, e)
end
