Webter how big a matrix is? I bring to mind a question from the midterm exam. Namely: Suppose that a vector ~t 0 represents a temperature state of a discretely approximated system at time 0. Then there is a matrix M and a vector ~bsuch that the temperature distribution an hour later is represented by ~t 1 = M ~t+ b: In our example, we had M= 2 … WebAn m×n matrix A =[aij] is a rectangular array of numbers arranged in m rows and n columns. The entry in the ith row and jth column is written aij. More generally, such an array, whose entries are allowed to depend on an indeterminate t, is known as a matrix function. Matrix functions can be used to formulate systems of differential equations. WebUse plain English or common mathematical syntax to enter your queries.
