I'm having trouble getting an array to display right, because one of the numbers keeps showing up in the wrong place. Is there any way to move it from one part of the array to the end, without swapping it with another variable?

Here's an example of what I have (with T being an array):

T = 1 5 77 10 15 20 25 33

Here's an example of what I need:

T = 1 5 10 15 20 25 33 77

Thank you kindly in advance!

在 MATLAB Online 中打开

indexToMove = 3;
T = [1 5 77 10 15 20 25 33];
T = [T(1:indexToMove-1), T(indexToMove+1:end), T(indexToMove)]
T = 1×8
     1     5    10    15    20    25    33    77

在 MATLAB Online 中打开

T = [1 5 77 10 15 20 25 33];
T1 = sort(T)      % Method 1
T1 = 1×8
     1     5    10    15    20    25    33    77
T2 = T([1:2 4:end 3])   % Method2
T2 = 1×8
