please how to inrement a length of the beam by 0.01in this simpl equation this has not given the hand

for  x=1:l+1;
  phi(x,m)=sin((x-1)*pi*m/l);

[Azzi Abdelmalek]

What do you mean?

[sihem chaib]

i must put an increment : x=1:0.001:l+1 but this does not work

Answer 1

[Azzi Abdelmalek]

Maybe you want

l=100
for x=1:l+1;
    for m=1:10 
  phi(x,m)=sin((x-1)*pi*m/l);
    end
end
plot(phi)

Sihem commented

l is limited by an equation in my parametres l=50 and think you for your answer

my eqation is combined by tow equations with tow variabl t and x when i write my equation with out increment the graph is Breaked

[Azzi Abdelmalek]

l=50
x=1:0.001:l+1;
for ii=1:numel(x)
  for m=1:10
  phi(ii,m)=sin((x(ii)-1)*pi*m/l);
  end
end
plot(phi)

%or maybe

plot(phi')
