% Since there are 4 elements in each row, we try 4 %d format strings. % This can be fixed by putting the transpose, S' in the fprintf statement: The printed matrix is the transpose of matrix S. We see that it read the 3 values in the first column, but printed them in the first row. % Since there are 3 elements in each row, we try 3 %d format strings. Consider this example of a square matrix.: This can result in printing the transpose of a square matrix. If you have more than one format string, it will print as many values as there are format strings, then cycle back to the beginning of the format string to continue printing the remaining characters. If your message has a single format string, they will be printed as a column. This means that shorter numbers will be padded but longer numbers will be allowed to extend beyond the specified field width when this is necessary to maintain the specified precision. However, fprintf() can print all of the values with a single instruction. The field width parameter of sprintf and fprintf (e.g., 'n' in 'sprintf ('nf',1234)') specifies the minimum width of the field. With this approach, you would only use the \n for the last element of a row. One way to print the values of a matrix is to use nested for loops and print one value at a time. Since both the mean and the standard deviation are between 1 and 10, we want 3 significant digits to get 2 decimal places.
Hint: num2str() lets you specify the number of significant digits, as opposed to the number of decimal places.

This video explains how to display a number with the disp() command:Ĭreating formatted outputs using the disp() command in MATLAB. No credit if you you just type in the values. Make a similar output using disp( ) and num2str( ) functions with a single disp() function. No credit if you you just type in the values.Ĥ. You need to use 2 proper %f format strings. Hint: a number like 1.34 needs 4 characters, so use %4.2f Where x.xx and y.yy will be replaced with your values.
Matlab fprintf vs sprintf code#
Display the mean and standard deviation values to the screen using fprint( ) with a %f format code (with 2 decimal places) to create a string like: Compute the mean and standard deviation of the vector.ģ. X = randi(6,1,36) % Create a vector with uniform random integers between 0 and 6.Ģ.
