What’s the problem with the MATLAB program?

??? Error using ==> mrdivide: Matrix dimensions must agree. Error in ==> NonIsothermTR>Equations at line 81: dx1dz = rhoB*r1*30.66 /(yA0*G); Error in ==> odearguments at line 111: f0 = feval(ode,t0,y0,args{:}); % ODE15I sets args{1} to yp0. Error in ==> ode45 at line 173: = ode45(@Equations, , ); This error message appears when running a MATLAB program to solve a system of differential equations; it seems to be related to inconsistent array dimensions. No arrays have been defined yet – can someone help identify what the problem is?
The mrdivide function was used incorrectly; the dimensions of the matrices do not match during the calculation
I don’t have this function in my M file. Is it an internal function generated when calling ODE45? I’m not very familiar with Matlab either; I modified existing programs to carry out numerical simulations of fixed-bed reactors. The original programs worked fine, but after I changed a few parameters, they stopped working.
