Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 2-by-1.

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?
