HI,
Over the years I have purchased Matlab 2016b, Matlab R2021a, and Matlab R2024a. All home edition versions.
I can run this code on my Matlab 2016b, Matlab R2021a versions and produce my little video (see below):
clear
clc
writerObj = VideoWriter('C:\Users\CefnG\Documents\MATLAB\EExp5151_split','MPEG-4');%Name of video file
open(writerObj);
fig1 = figure(1);
load EExp5151_split.TNO %Read in the file generated by Microcap 12 -No headers
d1 = EExp5151_split;
timestamp = d1(:,1);
d1(:,1)=[];%Remove time
rws=51; %Get this number from the Microcap 12 netlist
cols=51; %Get this number from the Microcap 12 netlist
s=size(d1);
d1ct=1;
for k = 1:s(1)
for j=1:rws
for i=1:cols
Z(j,i)=d1(k,d1ct);
d1ct=d1ct+1;
end
end
d1ct=1;
x=1:1:rws;
xx=1:1:rws;%put in an increment for spline command
for p=1:cols
y=Z(:,p);
yy(:,p)=spline(x,y,xx);
end
syy=size(yy);
x=1:1:cols;
xx=1:1:cols; %put in an increment for spline command
for p=1:syy(1)
y=yy(p,:);
Zz(p,:)=spline(x,y,xx);
end
s2=size(Zz);
mztb=zeros(1,s2(2)+2);
sidez=zeros(s2(1),1);
Zc=[mztb;sidez Zz sidez;mztb];%put some 0's around the data
[X,Y] = meshgrid(1:1:s2(2)+2, 1:1:s2(1)+2);
mesh(X,Y,Zc);
view([-37 77])
title('53 by 53 grid (spline = 1)')
xlabel('X')
ylabel('Y')
txt = ['Time: ' num2str(timestamp(k,1)) ' secs'];
text(-15,-5,txt)
axis([1 s2(2)+2 1 s2(1)+2 -3 3])
F=getframe(fig1);
%write the current frame to the writer object
writeVideo(writerObj,F)
end
%Close the writer object. File appers in current folder
close(writerObj);
disp('Video File Written')
Video it produces: https://drive.google.com/file/d/1u9qJqhz58xAxLbSwOZpe2oxqQeWbsi4e/view?usp=sharing
This what I get on my Matlab R2024a version:
Warning: Function strings has the same name as a MATLAB built-in. We suggest you rename the function to avoid a potential
name conflict.
> In Zsplined (line 6)
Execution of script strings as a function is not supported:
C:\Users\pc1\OneDrive\Documents\MATLAB\strings.m
Error in matlab.graphics.internal.configureAxes
Error in matlab.graphics.internal.configureAxes
Error in mesh (line 117)
matlab.graphics.internal.configureAxes(cax,x,y,z);
Error in Zsplined (line 46)
mesh(X,Y,Zc);
What can I do about the mesh error?

You have your own script named strings.m. MathWorks introduced a strings function in release R2016b and this function appears to be used by some of the internal tools that configure an axes before mesh creates a plot on it. [I don't know when that internal tool started using strings, likely after release R2021a since you indicated that did not error.] Rename your strings.m script file to avoid the conflict.

Thanks, I forgot that I had creared a strings.m a few years ago (using chebfun).
