Here is a snippet of my code:
clc;
figure
x=[30.423 32.562 33.356 34.892];
x1=[30.63 32.822 33.556 34.893];
x2=[30.83 32.962 33.856 34.895];
y=[0.004 0.003 .002 .001];
axis([20 45 1 4])
plot(y,x,'-bo',y,x1,'g-*',y,x2,'-k^','linewidth',1.5,'markeredgecolor','r')
xlimit=[20 40];
xlabel ('Noise level(salt & pepper)');
ylabel ('PSNR');
legend('plain image','cipher image');
It shows output as this error when it hits line 54 of my code:
Error using legend (line 278)
Attempt to execute SCRIPT flip
as a function:
C:\Matlab\bin\R2020a\bin\matlab\flip.m
Error in entropy_graph (line 54)
legend('plain image','cipher
image');

Can you tell us what you see if you type this command at the Matlab prompt?
which -all flip
I suspect that you have created a script called flip.m that is somewhere on your path (probably in C:\Matlab\bin\R2020a\bin\matlab\flip.m where there is normally no flip), or in the current working directory. You should rename it since flip is a Matlab function and (apparently) is used by the legend function.

C:\Matlab\bin\R2020a\bin\matlab\flip.m
Is not a flip.m supplied by Mathworks. flip is a built-in in your version, with a typical "which" location of
C:\Program Files\MATLAB\R2020a\toolbox\matlab\elmat\flip
You might need to reinstall MATLAB completely.

I just copied and pasted and it works fine:
clc;
figure
x=[30.423 32.562 33.356 34.892];
x1=[30.63 32.822 33.556 34.893];
x2=[30.83 32.962 33.856 34.895];
y=[0.004 0.003 .002 .001];
axis([20 45 1 4])
plot(y,x,'-bo',y,x1,'g-*',y,x2,'-k^','linewidth',1.5,'markeredgecolor','r')
xlimit=[20 40];
xlabel ('Noise level(salt & pepper)');
ylabel ('PSNR');
legend('plain image','cipher image');
The error must lie somewhere in the intervening 50 lines you did not show us.
