min( ) MATH/List menu min(expression1, expression2) ⇒ expression min(list1, list2) ⇒ list min(matrix1, matrix2) ⇒ matrix Returns the minimum of the two arguments. If the arguments are two lists or matrices, returns a list or matrix containing the minimum value of each pair of corresponding elements. min(list) ⇒ expression Returns the minimum element of list. min(matrix1) ⇒ matrix Returns a row vector containing the minimum element of each column in matrix1. Note: See also fMin() and max(). min(2.3,1.4) ¸ min({1,2},{ë 4,3}) ¸ 1.4 {ë 4 2} min({0,1,ë 7,1.3,.5}) ¸ ë7 min([1,ë 3,7;ë 4,0,.3]) ¸ [ë 4 ë 3 .3] mod( ) MATH/Number menu mod(expression1, expression2) ⇒ expression mod(list1, list2) ⇒ list mod(matrix1, matrix2) ⇒ matrix Returns the first argument modulo the second argument as defined by the identities: mod(x,0) x mod(x,y) xì y floor(x/y) When the second argument is non-zero, the result is periodic in that argument. The result is either zero or has the same sign as the second argument. mod(7,0) ¸ 7 mod(7,3) ¸ 1 mod(ë 7,3) ¸ 2 mod(7,ë 3) ¸ ë2 mod(ë 7,ë 3) ¸ ë1 mod({12,ë 14,16},{9,7,ë 5}) ¸ {3 0 ë 4} If the arguments are two lists or two matrices, returns a list or matrix containing the modulo of each pair of corresponding elements. Note: See also remain(). MoveVar CATALOG MoveVar var, oldFolder, newFolder Moves variable var from oldFolder to newFolder. If newFolder does not exist, MoveVar creates it. {1,2,3,4}!
