I just tried to plot this but the space after Nozzle Number is being removed?
for i=1:19
plot(pressures_spray_angle,spray_angle(i,:),'-*','LineWidth',2,'DisplayName',strcat('Nozzle Number ',num2str(nozzle_numbers(i))));
Also I tried to concatenate with a + and that did not work.
Is this a MATLAB 2022b thing? If so, please name out the software engineer who implemented it and approved it for accountability purposes :D

"Is this a MATLAB 2022b thing?"
No, STRCAT has always trimmed trailing whitespace from character arrays, as the last example from this 2012 archive of the documentation shows:
Every archived version of the documentation shows/explains this.

"For character array inputs, strcat removes trailing ASCII whitespace characters: space, tab, vertical tab, newline, carriage return, and form feed. For cell array and string array inputs, strcat does not remove trailing white space."
use [] or horzcat please
tx1='hello ';
tx2='world ';
[tx1 tx2 num2str(number)]
ans = 'hello world 0.021847'
ans = 'hello world 0.021847'
ans = 'helloworld0.021847'
using + is only suported for strings not character arrays:
"hello " + "world"
ans = "hello world"
class("hello " + "world")
ans = 'string'
ans = 'char'
