The matlab syntax for writing an exponent in an axis label is

ylabel('e^t')

but when I try to do this on my figure I get the following error:

>> ylabel('e^t')

Warning: Error updating Text.

String scalar or character vector must have valid interpreter syntax:

e^t

Instead of getting an exponent, my axis label shows 'e^t' How do I resolve this issue?

在 MATLAB Online 中打开

ylabel('e^t')

What MATLAB version are you using?

Please show the exact code that you are calling.

Please show the complete output of this command:

which ylabel -all

Do you receive that error running just that one line of code? Or can you only reproduce it with more lines (hopefully just a few lines)? Please post a small and self-contained example that you can run (in a fresh session of MATLAB, newly started) that produces the warning.

xlabel('e^{(t/10)}')

The one thing I'm thinking of that might cause this with just that line of code is if you've change the default Interpreter property for text objects first.

f = figure;

set(f, 'DefaultTextInterpreter', 'LaTeX')

xlabel('e^{(t/10)}')
