Hello
I have got this error message:
Error in cell2mat (line 36)
if isnumeric(c{1}) || ischar(c{1}) || islogical(c{1}) || isstruct(c{1})
Error in slope_centres (line 248)
C=cell2mat(Csurf{surface,g});
In each loop try, I want to get a specific array of the cell matrix Csurf (its indexing depend on the surface number and g) as numeric value, and use it as the input for the function Slide. The code is attached below. Any recommendation is highly appreciated.

for g=1:Nmc %number of monte carlo iterations
for i=1:nx+1
for j=1:ny+1
d(1)=sqrt((xc(i)-P(2,1))^2+(yc(j)-P(2,2))^2); % distance
d(2)=sqrt((xc(i)-P(3,1))^2+(yc(j)-P(3,2))^2); % distance
d(3)=yc(j)-P(2,2)+ H; % distance
R1=min(d);
R2=max(d);
DeltaR=(R2-R1)/nr;
cont=0;
for R=R1:DeltaR:R2
cont=cont+1;
surface=surface+1
C=cell2mat(Csurf{surface,g});%------>line36
[Fb]=slide(rho,C,P,xc(i),yc(j),R,n,KH,KV,MD);
FF(cont,1)=R;
FF(cont,2)=Fb;
end
FFb(i,j)=nanmin(FF(:,2));
for Cont=1:cont
if FFb(i,j)==FF(Cont,2)
RR(i,j)=FF(Cont,1);
end
end
end
end
FFFb=nanmin(nanmin(FFb))
end

you do not show Csurc so it is difficult to say. Perhaps it is empty.

It's hard to tell because you haven't stated what Csurf contains. Yes, it's a cell matrix, but a cell matrix containing what?
Having said that, it appears the problem is likely that you are converting twice, using brace indexing and using cell2mat. I suggest you undo one of the conversions by changing ...
C=cell2mat(Csurf{surface,g});
to
C=Csurf{surface,g};
or
C=cell2mat(Csurf(surface,g));
