Matlab优秀例题之产生一个信息表
产生一个信息表产生并打印一个数据表是说明函数fprintf函数就用的好方法。下面的脚本文件产生1到10中的所有整数的平方根，平方，立方，并在一个表中显示数据，并带有合适的表头。% Script file: table.m%% Purpose:% To create a table of square roots, squares, and% cubes.%% Record of revisions:% Date Programmer Description of change% ==== ========== =====================% 12/20/98 S.

%
% Define variables:
% cube -- Cubes
% ii -- Index variable
% square -- Squares
% square_roots -- Square roots
% out -- Output array
% Print the title of the table.
fprintf(' Table of Square Roots, Squares, and Cubes\n\n');
% Print column headings
fprintf(' Number Square Root Square Cube\n');
fprintf(' ====== =========== ====== ====\n');
% Generate the required data
ii = 1:10;
square_root = sqrt(ii);
square = ii.^2;
cube = ii.^3;
% Create the output array
out = ;
% Print the data
for ii = 1:10
fprintf (' %2d %11.4f %6d %8d\n',out(ii,:));
