Hello everyone, could someone help me with the error that I have in the next code?. The problem that I have is related with the title that I indicated before.
m=10; %Número de simulaciones
a=1; %Altura del talud.
hw=1; %Profundidad a la que se encuentra el nivel freático desde la superficie.
g=20; %Peso unitario del suelo
c=10; %Cohesión promedio.
fi=25; %Águlo de cohesión promedio.
b=15; %Ángulo de inclinación del talud.
covc=.3; %Covarianza de la cohesión.
covfi=.1; %Covarianza del tan(fi).
dstdc=covc*c; %Desviación estandard de c'
dstdfi=covfi*tand(fi); %Desviación estandard de tan(fi)
fs=zeros(m,a);
mfs=zeros(m,a);
dfs=zeros(m,a);
for h=1:a
for n=1:m
cfs (n,:)= (c+(-dstdc+(dstdc+dstdc)*rand));
fifs (n,:)= (tand(fi)+(-dstdfi+(dstdfi+dstdfi)*rand));
fs(n,h) = (1./(g*h*sind(b)*cosd(b))).*cfs+(cotd(b)-((9.81*(h-hw))./(g*h*tand(b)))).*fifs;
end
end

cfs and fifs are both 2 values, so you're trying to stick two values into one index.
Change the fs line to this and see what you learn:
value = (1./(g*h*sind(b)*cosd(b))).*cfs+(cotd(b)-((9.81*(h-hw))./(g*h*tand(b)))).*fifs
fs(n,h) = value;

Thank you for the answer.
I tried this but it didn't work. What I pretend is the fs line save the values of each loop, and in the way that you propose me, I can´t do that. Could exist another way of do that?
