What is a transpose?
Short answer. A matrix with its rows turned into columns.
Can you add matrices of different sizes?
No. They must have the same rows and columns.
Transpose
| Original | Transpose |
|---|---|
| 1 2 3 | 1 4 |
| 4 5 6 | 2 5 |
| - | 3 6 |
Remember
| t[r][c] = m[c][r] |
| Add: same size matrices |
Can you flip a matrix on its diagonal? Yes, that is the transpose. Row one two three becomes column one. Two rows of three become three rows of two. Transpose swaps the indexes. Add only same size matrices.
