00:05 demo a prebuilt version of the application
00:14 add 2 matrices (both must have same size. add elements in same position)
00:52 subtract 2 matrices (both must have same size. subtract elements in same position)
01:28 multiply 2 matrices (both must have matching inner dimension. size of resulting matrix obtained by dropping middle dimension)
02:32 step by step example of multiplying 2 matrices
04:37 scalar add (operation applied to each element in matrix)
05:12 scalar subtract (operation applied to each element in matrix)
05:33 scalar multiply (operation applied to each element in matrix)
05:55 scalar divide (operation applied to each element in matrix)
06:25 code the application
07:43 scalar operations are called this way because the relative values of the elements in matrix do not change only the scale changes
08:49 matrix scalar operations code
11:37 add and subtract matrices code
12:56 multiply matrices code
13:46 code Driver class for matrix functionality testing
14:27 test run completed application
