How to print a variable in matlab
Feb 24, 2017 · Answers (2) The return is 6.5003e-05 and the standard deviation is 0.0207. read the fprintf help page to get printing options based on the number formats. It means that your variable (s) me and/or st are structures instead of numerical values. Check it. I am unable to print the values in double format, suppose if I have a value b=0.394944961213358 [1x1 double] it shows ??? Undefined function or method 'fprinf' for input arguments of type 'char'. How can I round it to first four decimal values ( as 0.3949) and print it to a file.I know the disp command shows the values without the variable name and the fprintf command allows you to print a string with variables. But I'm trying to sort variables from highest to lowest and I want to get Matlab to print their corresponding variables rather than just giving me numbers. thanks!
