I can't figure out this array issue using an integral command

Im trying to figure out an integral from -inf to inf on a meshgrid. I keep getting an error saying arrays dont match. How do I fix this issue?
To be clear I have a meshgrid for space and time [ZZ Time]. I have an integral that needs to be calculates at every ZZ and Time where zz is from -inf to inf
ZZ=linspace(0,100,10);
Time=linspace(0,100,10);
zeta=1;
D=.36;
con=(4*D*Time);
fun=@(zz) (pi*.con).^(-1/2)*exp(-(ZZ-zz).^2/(con)).*exp(-abs(ZZ)/zeta);
output=integral(fun,-Inf,Inf)
Arrays have incompatible sizes for this operation.
Error in project>@(zz)(pi*con).^(-1/2)*exp(-(ZZ-zz).^2/(con)).*exp(-abs(ZZ)/zeta) (line 16)
fun=@(zz) (pi*con).^(-1/2)*exp(-(ZZ-zz).^2/(con)).*exp(-abs(ZZ)/zeta);

Use the 'ArrayValued' name-value pair —
format longE
ZZ=linspace(0,100,10);
Time=linspace(0,100,10);
zeta=1;
D=.36;
con=(4*D*Time);
fun=@(zz) (pi*con).^(-1/2)*exp(-(ZZ-zz).^2/(con)).*exp(-abs(ZZ)/zeta);
output=integral(fun,-Inf,Inf, 'ArrayValued',1)
.

The 'ArrayValued' option is listed on the integral function's documentation page, specifically in the Input Arguments section (the Name-Value Arguments subsection.)
