Plot 4 arrays all of them contain NaN value. How do you plot it smoothly.

Here is the code:

lw=2
plot(Sig1,'LineWidth',lw,'Color',[1 0.76 0])
hold on
plot(Sig2,'r','LineWidth',lw)
hold on
plot(Sig3,'g','LineWidth',lw)
hold on
plot(Sig4,'b','LineWidth',lw)
hold off

One option is to use the fillmissing function.

Example —

sig1 = [rand(1,10) NaN];
sig2 = [rand(1,10) NaN];
sig3 = [rand(1,10) NaN NaN];
sig4 = [rand(1,10) NaN];
sigv = [sig1 sig2 sig3 sig4];
sigvfm = fillmissing(sigv, 'linear');
figure
plot(sigv, 'b', 'LineWidth',1.5)
hold on
plot(sigvfm,'r')
hold off.
