Why do I keep getting this error for subplot? Am I missing a toolbox or is the code wrong?

Error using subplot

Unknown command option.

Error in (line 136)

h = subplot(2,1,[.12 .08],[.10 .08],[.12 .02])

Do you want the subplot spacing to be more compact ? or working with the below custom function ?https://in.mathworks.com/matlabcentral/fileexchange/27991-tight_subplot-nh-nw-gap-marg_h-marg_w

if so, then you need to call that function as given in instruction

[ha, pos] = tight_subplot(2,1,[.12 .08],[.10 .08],[.12 .02])

[Isabella Sciullo]

figure(2)

[ha, pos] = tight_subplot(2,1,[.12 .08],[.10 .08],[.12 .02]);

axes(ha(1)); box on; plot(angle0,Cp_exact,'b',beta,Cp,'r^');

grid; legend('C_p (exact)', 'C_p (SPM)');

title(['Fig. 2 Comparison of C_p and V_s (n = ' num2str(n) ', R = ' num2str(R) 'm)']);

xlim([0 2*pi]); set(gca,'xtick',0:pi/2:2*pi);

set(gca,'xticklabel',{'0','\pi/2','\pi','3\pi/2','2\pi'});

xlabel('\beta'); ylabel('C_p')

axes(h(2)); box on; plot(angle0,(Vs_exact),'b',beta,(Vs),'r^');

grid; legend('V_s (exact)', 'V_s (Source panel method)');

xlim([0 2*pi]); set(gca,'xtick',0:pi/2:2*pi);

set(gca,'xticklabel',{'0','\pi/2','\pi','3\pi/2','2\pi'});

xlabel('\beta'); ylabel('V_s [m/s]')

I'm not sure if I set it up right but

Please read the documentation of the command: subplot or

doc subplot

You call this command like subplot(m,n,p), where m and n are the numbers of rows and columns, and p is the index of the subplot.

What do you expect the input [.12 .08],[.10 .08],[.12 .02] to do?
