Learn more about format long, fprintf, fprintf format MATLAB In matlab specifying the format long there is not any problem. It can find the number value but can't find the variable x which equals that value. Learn more about format long 2015 MATLAB always displays integer data types to the appropriate number of digits for the data type. There is a bit more overhead compared to built-in functions (making built-in's usually, but not always, faster than an analagous .mex function). I changed the format of the script file from the default to long, and when I type a variable name into the command window it outputs in long format, but not when I try and output it using fprintf. x is a column vector that I want the results of in long format, each output in the same line as their variable names.
