hello,
I am trying to write to screen a set of variables with mixed types. I have the code below
and I get the following display:
d=0.7874 mm , epsr=2.1 >>
a='d=0.7874 mm , epsr=2.1';
m=3;
k=7;
u=7.853535;
fprintf('%s %i \t %10.5f \n',[a m u])
d=0.7874 mm , epsr=2.1□□
help would be appreciated.
Thank you

HI @Robert Jones
It looks like you're trying to print a string along with integer and floating-point variables using fprintf. The issue arises because you're trying to concatenate different types into a single array, which fprintf doesn't handle well. Instead, you should pass each variable separately to fprintf.
Here's how you can modify your code to correctly display the variables:
a = 'd=0.7874 mm , epsr=2.1';
m = 3;
k = 7;
u = 7.853535;
% Use fprintf with separate arguments for each variable
fprintf('%s %i \t %10.5f \n', a, m, u);
d=0.7874 mm , epsr=2.1 3 7.85353
This will correctly print the string a, the integer m, and the floating-point number u in the desired format.
If you want to include the variable k as well, you can add it to the fprintf statement:
fprintf('%s %i \t %i \t %10.5f \n', a, m, k, u);
d=0.7874 mm , epsr=2.1 3 7 7.85353
This way, each variable is passed as a separate argument to fprintf, ensuring they are printed correctly.
Refer to the following doc:
I hope this helps.
