A diagonal matrix is both upper and lower triangular. Tips Use the triu function to produce upper triangular matrices for which istriu returns logical 1 (true). The functions isdiag, istriu, and istril are special cases of the function isbanded, which can perform all of the same tests wit...

5.2.3 Triangular matrices and algebra of triangular matrices A matrix with all elements under/above the main diagonal equal to zero is called an upper/lower triangular matrix. A unit triangular matrix is triangular matrix with 1s on the main diagonal. There are a few useful properties about pro...
I would like to have a square matrix (4x4) with this data where the upper triangular matrix is the percentage of similarity and the lower triangular matrix the times that were compared, like this: 테마복사 0 50* 25 40 4* 0 25 40 4 4 0...
High ValenceANDLow Arousal: Lower Arousal values within the context of high Valence indicate a state of calmness and positive emotion. This relaxed and positive condition was labeled as “Relaxed”. Patients in this state were at ease, experiencing a pleasant and tranquil interaction with the robot...
