GROWTH

Set of y-values already known in the relationship y=b*mx. If the array known-ys is a single column, then each column of known-xs is interpreted as a separate variable. If the array known-ys is a single row, then each row of known-xs is interpreted as a separate variable.

Set of x-values that might already be know in the relationship y=b*mx. The array known-xs can include one or more sets of variables. If only one variable is used, known-ys and known-xs can be ranges of any shape, as long as they have equal dimensions. If more than one variable is used, known-ys must be a vector (that is, a known-ys with a height of one row or a width of one column). If known-xs is omitted, it is assumed to be the array {1,2,3,...} that is the same size as known-ys.

A set of new x-values for which GROWTH is to return corresponding y-values. new-xs shall include a column (or row) for each independent variable, just as known-xs does. So, if known-ys is in a single column, known-xs and new-xs shall have the same number of columns. If known-ys is in a single row, known-xs and new-xs shall have the same number of rows. If new-xs are omitted, it is assumed to be the array {1,2,3,...} that is the same size as known-ys.
