How to tabulate the values?

I=[-40 -30 -20 -10 0 10 20 30 40];
w=[0.035 0.5 1 1.25 1.5];
h=1.57;

I_len=length(I);
w_len=length(w);

for b=1:w_len 
  d=w(b);

for c = 1:I_len 
a = I(c);

T=215.3*a^2*d^-1.5*h^-1;
end
end

This is my code.

how do I tabulate the results of a,d,h,T and plot the graph for the same?

I=[-40 -30 -20 -10 0 10 20 30 40];
w=[0.035 0.5 1 1.25 1.5];
h=1.57;
I_len=length(I);
w_len=length(w);

T = zeros(w_len,I_len) ;
for b=1:w_len
    d=w(b);
    for c = 1:I_len
        a = I(c);
        T(b,c)=215.3*a^2*d^-1.5*h^-1;
    end
end

[X,Y] = meshgrid(I,w) ;
surf(X,Y,T)

Can you explain me what did you do in the above code?

because I had tried with mesh grid and had used sliceomatic and I got an error with it.

so can you tell me?

[KSSV]

It is self explanatory.......variables I, w are introduced in meshgrid to make it a matrix. T is initialized. In fact, you need not to use meshgrid, with T as matrix itself, it can be plotted. Simply try:

surf(I,w,T)

Okay thank you

Thanks is accepting and/or voting the answer. :)

Your question is not clear.

1:Graph between what parameters you want to plot?

2:In your For loop you are assigning every element of array to variable d and b. You are neither using them anywhere nor storing them. what you want to do with those variable?

[Sachin Shridhar Bhat]

1 - Graph between a,d,h,T

2- In for loop I am assigning each variable of w to d and I to a . And of course I am using those values to calculate the final T value in the equation below.
