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. 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. ANSI specification X3.159-1989: " Programming Language C," ANSI, 1430 Broadway, New York, NY 10018.\) Mimic dice rolls Ritchie, The C Programming Language, Second Edition, Prentice-Hall, Inc., 1988. Line termination character on all platforms Left-justifies the converted argument in its field.Ī digit string specifying the minimum number of digits to be printed.Ī digit string including a period (.) specifying the number of digits to be printed to the right of the decimal point. Other characters can be inserted into the conversion specifier between the % and the conversion character. Hexadecimal notation (using uppercase letters A- F) Hexadecimal notation (using lowercase letters a- f) The more compact of %e or %f, as defined in. Tables The following tables describe the nonalphanumeric characters found in format specification strings.Ĭonversion characters specify the notation of the output.Įxponential notation (using a lowercase e as in 3.1415e+00)Įxponential notation (using an uppercase E as in 3.1415E+00) Reinitializing, through any additional matrix arguments. It is then cycled in a similar manner, without Theįormat string is cycled through the elements of A (columnwise) until all theĮlements are used up. sprintf is vectorized for the case when input matrix A is nonscalar. The underlying C data type is a double rather than an unsigned integer.įor example, to print a double-precision value in hexadecimal, use a formatĢ. The underlying C data type is a float rather than an unsigned integer. The following nonstandard subtype specifiers are supported for conversion Remarks The sprintf function behaves like its ANSI C language sprintf() namesake with certain exceptions and extensions. Returns an error message string errmsg if an error occurred or an empty matrix if an error did not occur. It can contain ordinary alphanumeric characters along with escape characters, conversion specifiers, and other characters, organized as shown below:įor more information see "Tables" and "References." = sprintf( format,A.) The format string specifies notation, alignment, significant digits, field width, and other aspects of output format. sprintf is the same as fprintf except that it returns the data in a MATLAB string variable rather than writing it to a file. Sprintf (MATLAB Function Reference) MATLAB Function Referenceįormats the data in matrix A (and in any additional matrix arguments) under control of the specified format string, and returns it in the MATLAB string variable s.
