How to choose only certain values my matrix answer

3 次查看(过去 30 天)
Hi. Grateful for any help please.
My output is in matrix, say 400 563 674 904 789
Now i want to use 563 to 904, as a matrix in another algorithm without me redefining it.
Many thanks

A=[400,563,674,904,789];
B=A(A>=563&A<=904);

My B above gives you that output. If you want a column vector just add an apostrophe.
A=[400,563,674,904,789];
B=A(A>=563&A<=904)';

A=[400,563,674,904,789];
idx1 = find(A>=563, 1, 'first');
idx2 = find(A>=904, 1, 'first');
A(idx1:idx2)
but I suspect what you might be looking for is:
A(2:end-1)
