i have to write a program where i have 4 data cuboid1,cuboid2,cuboid3,cuboid 4 and each cuboid has length ,breadth and thickness i have write loop in such a way .......when i run this code

it selects one cuboid at a time and when each cuboid is selected ...by default its specification is also selected and later it is checked whether it is conductor or insulator

data={cuboid1,cuboid2,cuboid3,cuboid4);

specifiation cuboid its length breadth and thickness

length=[5 6 7 8 9]

breadth=[5 6 7 8 9]

thickness1=[5 6 7 8 9]

thickness2=[5 6 7 8 9] using for loop

there are two thickness for each cuboid...first it has to take th1 then execute

else th2 execute

The question is not clear. Where are the "40 data lists"? Why has one cuboid 5 values for length, an breadth and 2 different thickness values?

What is the actual question? Which problem do you want to solve in Matlab?

data={cuboid1,cuboid2,cuboid3,cuboid4);

specifiation cuboid its length breadth and thickness

cuboid1=[length=5,breadth= 6,thickness=9]

cuboid2=[length=7,breadth= 8,thickness=9] like wise its for cuboid3 and 4

how to write in loop using for loop

在 MATLAB Online 中打开

cuboid1 = struct('length', [5 6 7 8 9], 'breadth',  [5 6 7 8 9], 'thickness1', [5 6 7 8 9], 'thickness2', [5 6 7 8 9]);
cuboid2 = similar code
data = {cuboid1,cuboid2,cuboid3,cuboid4);
num_cuboids = length(data);
for idx = 1 : num_cuboids
   this_cuboid = data{idx};
   this_length = this_cuboid.length;
   this_breadth = this_cuboid.breadth;
   this_thickness1 = this_cuboid.thickness1;
   this_thickness2 = this_cubuoid.thickness2;
   results(idx,1) = classify_insulation(this_length, this_breadth, this_thickness1);
   results(idx,2) = classify_insulation(this_length, this_breadth, this_thickness2);
end

thank you sir..but after this step i also have to find if results is conductor or insulator.

for example i have assigned conductor=0;

insulator=1;

if result is conductor

then resistivity=1000ohm

a=5;

b=6;

else if insulator

a=5;

b=6

...how can i write code in for loop format......because everything should repeat for 40 cuboids with different length breadth and thickness

(and everytime code has to select one cuboid at a time ..execute all instructions and perfom loop for everything and then follow same routine for 2nd cuboid and so on...)
