I have a matrix of zeros and when they are multiplied by a negative number and printed, the results turn out to be zeros with a negative sign in front of it. of the value shows up as 0. 0000 then MATLAB has not stated that they are zeroHi! I need to write a function that takes in numerical data as input argument and prints a message to the command window stating if the number is positive, negative or zero. matlab fprintf negative number

The fprintf command is particularly useful. It does not take arguments in the traditional sense, but instead uses format strings to indicate how text and numbers should be printed. Here is how we might use fprintf to print a table of numbers. In this example, we print the same number in In all likelihood, if V is complex, blockofdata will also be complex (although the imaginary parts of the real numbers will be 0), considerably complicating your desire to use otherwise efficient matrix arguments to fprintf. If you use fprintf to convert a MATLAB double into an integer, and the double contains a value that cannot be represented as an integer (for example, it contains a fraction), MATLAB ignores the specified conversion and outputs the value in exponential format.matlab fprintf negative number Hence Matlab did what you asked; used the minimum possible to fill the field resulting in the shifting of position when the positive sign wasn't needed. AFAIK, there's no standard way in C to write the threedigit exponent field; if you must have that you'll have to write it specifically.
