Formatted Output

Using num2str

num2str( value, precision )

Examples

value = 8/3;
matrix = [ 1 : 3; 4 : 6 ] / 3;

disp(num2str(value))

disp(num2str(matrix))

disp(num2str(value, 16))

disp(num2str(matrix, 16))

Using fprintf

fprintf( formatString, var1, var2, ... )

Format strings

• s - string
• d - decimal integer
• f - fixed floating point
• e - scientific notation
• specifying width
• specifiying precision

Examples

heading = input('Enter heading: ', 's');
numValues = 15;
values = 2 : 3.5 : 83;
avg = mean(values);

fprintf('N = %d', numValues)


fprintf('* * * %s * * *\n', heading)


fprintf('%5d : %12.8f\n', values(1), avg)


fprintf('%5d : %12.8f\n', values(15), avg/3)


fprintf('%-5d : %12.8f\n', values(21), avg/5)
