求关于trapz函数的

sdutnuaa

clc
xx=-10:0.2:10;
tt=0.01:0.1:1;
tau=-0.5:0.001:0.5;
theata=2*(-tau./abs(tau)).*tau+1.1;
a=2;
[X,T,TAU]=meshgrid(xx, tt,tau);
F=theata.*1/2/2./sqrt(pi*T).*exp(-(X-TAU).^2/4/2^2./T);
js=0.2*trapz(tau,F);
waterfall(X(:,:,1),T(:,:,1),js)
运行后出现下列状况 是什么意思？该如何解决？谢谢啦
??? Error using ==> rdivide
Matrix dimensions must agree.

Error in ==> chuanre at 8
F=theata.*1/2/2./sqrt(pi*T).*exp(-(X-TAU).^2/4/2^2./T);
