display number as str in matlab

To convert a number to a string (char), you can use the num2str function in matlab. Here is an example:

main.m
num = 42;
str = num2str(num);
disp(str);
41 chars
4 lines

The output of this code will be:

main.m
42
3 chars
2 lines

If you want to format the string, you can use sprintf function. Here is an example:

main.m
num = 3.14159;
str = sprintf('%.2f', num);
disp(str);
54 chars
4 lines

The output of this code will be:

main.m
3.14
5 chars
2 lines

In this example, "%.2f" formats the number to 2 decimal places.
