![]() ![]() MATLAB for Engineers provides a clear and concise introduction. (\d) At least one digit, saves digit to group $2įinally, the matched text is replaced with E$1$2, that is the literal E, then group $1 (a minus sign if found E-, nothing if found E+) and the group $2 (a single digit). It is an interactive program that helps you with numeric computation and data visualization. This is better but I would like to use an 'engineering' notation where the output is formatted in powers of 10 3 millions, billions, trillions etc. \+?(-?) Either a + or a - if - then save to group $1Ġ* As many 0s as it can match, subject to. Say I have this number: 105000000, in this form I can't easily see how big it is, so using printf at a prompt I try using the 'scientific' notation: printf '.3E' 105000000 1.050E+08. format long x x 1.333333333333333 Using the format function only sets the format for the current MATLAB session. ![]() ![]() For example, x 1.3333 You can change the display in the Command Window or Editor using the format function. To explain, sprintf('%.E',x) formats x in scientific notation with E, e.g. Number format Follow 6 views (last 30 days) Show older comments Poul Reitzel on Dear Matlab Community I am facing a problem to convert a row of numbers to a string in a specific format. By default, MATLAB uses a 5-digit short format to display numbers. Here the symbol of tells MATLAB about the beginning of the format string. We can fix the first case with a token: f2 = Scanning over all the numbers of the files for num0:90 namestrcat(path. Does printf have an 'engineering' notation format for numbers Ask Question Asked 5 years, 9 months ago Modified 5 years, 9 months ago Viewed 4k times 7 Say I have this number: 105000000, in this form I can't easily see how big it is, so using printf at a prompt I try using the 'scientific' notation: printf '.3E' 105000000 1. Converts a numeric array into a string in the specified format. This is not ideal for all cases: > my_format(5) % Expect 5E0 MATLAB contains mathematical, statistical, and engineering functions that support most. You could use a combination of sprintf and regexprep. ![]()
