Hi, I want to use mesh to plot 3D grids with the format of mesh(x, y, z). My z is a 47*11 matrix, in which the 7 column actually has only 45 values, and I set the other 2 numbers as NaN in order to from a matrix with other columns. But when I plot the figure, the location of NaN is blank (see below).
Is there any method to fill these special locations? Thanks!

It would be best to have your data, however an illustration of the procedure using the fillmissing function is — .
x = 1:11;
y = 1:47;
z = y(:)*x
z = 47×11
1 2 3 4 5 6 7 8 9 10 11 2 4 6 8 10 12 14 16 18 20 22 3 6 9 12 15 18 21 24 27 30 33 4 8 12 16 20 24 28 32 36 40 44 5 10 15 20 25 30 35 40 45 50 55 6 12 18 24 30 36 42 48 54 60 66 7 14 21 28 35 42 49 56 63 70 77 8 16 24 32 40 48 56 64 72 80 88 9 18 27 36 45 54 63 72 81 90 99 10 20 30 40 50 60 70 80 90 100 110
figure
mesh(x, y, z)
grid on
title('Original')
z(20:25,5:7) = NaN; % Create Gaps
figure
mesh(x, y, z)
grid on
title('With Gaps')
z = fillmissing(z, 'linear');
figure
mesh(x, y, z)
grid on
title('Interpolated')
.
