Using variable as limiting index counts one less.

Hello fellow Mathworkers,

i encountered a strange behavior when reading from an array:

Let's say my array is A = zeros(1,100000) and i want B = A(1:50000) and C = A(50001:100000)

B and C are both 1x50000 double. That's what i want.

But when reading it like B = A(start:stop) and start = 1 and stop = 50000, B will be only 1x49999 double.

Is this a bug or am i missing something?

Thanks in advance!

Should i close the question or is this useful for others?

在 MATLAB Online 中打开

A = zeros(1,100000);
start = 1;
stop = 50000;
B = A(start:stop)
B = 1×50000
