MATLAB - 顯示數據

Question

所以我試圖計算並作爲附加的圖片（http://i.stack.imgur.com/b2DHd.png）這裏描述顯示的平均數據是我：

lakeData = load('C:\Users\Justin\Desktop\EGR2222\MATLAB\Data\LAKE_POWELL.txt'); 

year1= lakeData(:,1); 
year2= lakeData (:,2); 
year3= lakeData (:, 3); 
year4= lakeData (:, 4); 
year5= lakeData (:, 5); 
year6= lakeData (:,6); 
year7= lakeData (:,7); 
year8= lakeData (:,8); 

lakePowell = [year1, year2, year3, year4, year5, year6, year7, year8]; 
years = [2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007]; 
average = mean(lakePowell) 

fprintf('The average water level was %s in %s\n', average, years) 

我的問題是，我是新來的MATLAB和我不知道如何正確編寫我的fprintf語句以便一次打印所有數據。請幫忙！

Answer 1

您可能想循環遍歷average中的所有值和years中的所有值並打印它們。

此外，您將要使用%f和%d作爲格式，因爲它們是數字。

for k = 1:numel(years) 
    fprintf('The average water level was %f in %d\n', average(k), years(k)) 
end 

另一種選擇是來連接沿着第一維average和years，然後你可以調用fprintf一次。

combined = cat(1, average(:).', years(:).'); 
fprintf('The average water level was %f in %d\n', combined);
