Issue with sprintf () latex interpreter

In the below command, in the place of X=1, is it posiible to call the value that's been defined outside. I tried to use sprintf(), but was not successful.

a = 1;

text(20,2620,{'$[\alpha_{X=1]$'},'FontSize',28,'Color','b','Interpreter','latex');

text(20,2620,sprintf{'$[\alpha_{X='%3dmm',a}]$'},'FontSize',28,'Color','b','Interpreter','latex');

a = 1;
disp('Here''s how to include a single quote in a char vector')

Here's how to include a single quote in a char vector

disp("Here's how to include a single quote in a string array")

Here's how to include a single quote in a string array

fprintf("To include %c in the output of fprintf or sprintf, escape it: \\", '\')

To include \ in the output of fprintf or sprintf, escape it: \

text(0.5,0.25,sprintf('$[\\alpha_{X=''%3dmm''}]$', a),'FontSize',28,'Color','b','Interpreter','latex');
text(0.5,0.75,sprintf("$[\\alpha_{X='%3dmm'}]$",a),'FontSize',28,'Color','b','Interpreter','latex');

Thanks, Steven!!

Is it possible to remove the quote, I mean instead of X = '1mm' just like this X = 1mm

Sorry, I used as below.. Its okay now

text(0.5,0.75,sprintf("$[\\alpha_{X= %3dmm}]$",a),'FontSize',28,'Color','b','Interpreter','latex');
