[. . . ] Example · Store lists {2, 7, 4} and {-3, -4, -1} in L1 and L2 respectively, and sort L1 and L2 in ascending order using list L1 as a key list. 135 Chapter 9: List Features 3 dim( dim(list) Returns the number of items (dimension) in the list. natural number dim(list name) Set the number of items (dimension) of specified list to the specified number. The existing values within the new dimensions remain as they are. 4 fill( fill(value, list) Enter the specified value for all the items in the specified list. Example · Set the dimension of list L6 to 4 and substitute 5 for all the items of list L6. 136 Chapter 9: List Features 5 seq( seq(equation, start value, end value[, increments]) target list name Makes a list using the specified equation, range (start value and end value) and increments. Example · Fill the list using the equation y = x2 ­ 8, where x increases from -4 to 4 by increments of 2. * If increment is omitted, the default value 1 is used. 6 cumul cumul list Sequentially cumulates each item in the list (for Advanced mode only). Example · Set the list L1 to {4, 2, 7}, and obtain the cumulated list L1. · Cumulate the above result. 7 df_list df_list list Returns a new list using the difference between adjacent items in the list. Example · Set the list L1 to {4, 2, 7}, and calculate the difference between adjacent items. 137 Chapter 9: List Features 8 augment( augment(list 1, list 2) Returns a list appending the specified lists. Example · Obtain the list appending L1 ({4, 2, 7}) and L2 ({-1, -3, -4}). 9 listmat( listmat(list 1, . . . , list n, matrix name) Makes a matrix using the specified list as column data, stored under the specified matrix name (for Advanced mode only). Example · Make a matrix mat A using list L1 as the first column and list L2 as the second column. * This function is the same as listmat of the OPE menu in the MATRIX function. 0 matlist( matlist(matrix name, list name 1, . . . , list name n) matlist(matrix name, column number, list name) Makes lists from the matrix (for Advanced mode only). This function is the same as "matlist" of the OPE menu in the MATRIX function. See page 128 for details. 138 Chapter 9: List Features Calculations using MATH Menus During the following explanations, the values of lists, L1 and L2 will be assumed to be: L1 = {2, 8, -4} L2 = {-3, -4, -1} 1 min( min(list) Returns the minimum value in the list. Example · Calculate the maximum value of the specified list L2. Note: min(list 1, list 2) max(list 1, list 2) If two lists are specified in parenthesis separated by a comma, then a list consisting of minimum (or maximum) values is returned. 3 mean( mean(list [, frequency list]) Returns the mean value of items in the specified list. Example · Calculate the mean value of list L1. 139 Chapter 9: List Features 4 median( median(list [, frequency list]) Returns the median value of items in the specified list. Example · Calculate the median value of the list L2. 5 sum( sum(list [, start number, end number]) Returns the sum of items in the specified list. sum(L1, 2) means sum all items from the second to the last of the list L1. 6 prod( prod(list [, start number, end number]) Returns the multiplication of items in the specified list (for Advanced mode only). Example · Calculate the multiplication of items in the list L1. prod(L1, 2) means multiplication of all items from the second to the last of the list L1. 140 Chapter 9: List Features 7 stdDv( stdDv(list [, frequency list]) Returns the standard deviation of the specified list items.
