I want to print the data on screen as shown below. I have a 1 x n double numeric vector. Let it contents be as follows.
n = [3.2,4.5,2.5,1.2,7.2];
using fprintf() statement i want to print it as follows:
1.3.2Hz 2.4.5Hz 3.2.5Hz 4.1.2Hz 5.7.2Hz
Is it possible to do so ?
As an example i have a cell array "k" of size 5 x 1. I was able to print this as:
2.4Hz 5.4Hz 3.5Hz 4.5Hz 1.8Hz
using the statement:
fprint("%s\t",string(k)+'Hz')
If anyone have idea on how to do this, share your thoughts.

You're almost there. When you call string on a non-scalar double array, each element of the double array becomes an element of the string array.
n = [3.2,4.5,2.5,1.2,7.2];
s = string(n)
The + operator when given two compatible string arrays concatenates them element-wise.
part1 = string(1:numel(n)) + ". "
If one of the inputs to + is a string array and the other a compatible double array, the double is converted to a string to reduce this to a previously solved problem (two compatible string arrays.)
part2 = part1 + n + " Hz"
No fprintf needed, though if you're doing this as part of an assignment that requires it:
fprintf('%s\n', string(1:numel(n)) + ". " + n + " Hz")

It worked. I have one more doubt. suppose i have value of 2.093750000000000 and i want it to make 2.09375 by dividing it with some value. While doing so, matlab replaces this value as 2.0938. How can i overcome this problem ?
