disp(X)displays the value of variableXwithout printing the variable name. Another way to display a variable is to type its name, which displays a leading “X =” before the value.
If a variable contains an empty array,dispreturns without displaying anything.
Here are three ways to display multiple variable values on the same line in the Command Window.
Concatenate multiple character vectors together using the[]operator. Convert any numeric values to characters using thenum2strfunction. Usedispto display the result.
name ='Alice'; age = 12; X = [name,' will be ',num2str(age),' this year.']; disp(X)
Alice will be 12 this year.
Usesprintfto create text, and then display it withdisp.
name ='Alice'; age = 12; X = sprintf('%s will be %d this year.',name,age); disp(X)
Alice will be 12 this year.
Usefprintfto directly display the text without creating a variable. However, to terminate the display properly, you must end the text with the newline (\n) metacharacter.
name ='Alice'; age = 12; fprintf('%s will be %d this year.\n',name,age);
