![]() We see that it read the 2 values in the first column and then the 2 values in the second column and printed them in the first row. % 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. ![]() However, fprintf() can print all of the values with a single instruction. 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. fprintf (fid, formatSpec, index, str1, str2, str3, str4, str5, index) This second approach takes approx 1 sec to write although it has. This first approach takes approx 4 seconds to write. Since both the mean and the standard deviation are between 1 and 10, we want 3 significant digits to get 2 decimal places. I was under the impression that using a single fprintf () instead of multiple would be efficient but that is not the case as evident from the codes below. 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. The function sprintf puts the formatted output in a string. No credit if you you just type in the values.Ĥ. The MATLAB function fprintf produces formatted output on the screen or in a file. 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. 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.
