Hi everybody, i'm trying to integrate/put in a double array of the size 16x16 to a cell array with the size 16x16. For example i want the value of the double array from (1,1) in the cell array on {1,1}.speed. Further down is my code so far. In the last lines i extract data from the cell array to a double array. What i want to do is to tourn this around, integrate the top_plate_speed into the top_plate cell array. After this i want to have in every element of the cell array the values of position_x, position_y and speed.
Code:
radius_bottom = 0.125; %[m]
speed_bottom = 200; %[U/min]
position_upper_x = 0; %[m]
position_upper_y = 0; %[m]
square_length_upper = 0.06; %[m]
speed_top = 100; %[1/min]
contourf_accuracy = 10; %Number of different fields in the figure
%%Convert Parameters
speed_bottom = speed_bottom/60; %convert from [U/min] to [U/sec]
speed_top = speed_top/60; %convert from [U/min] to [U/sec]
%%Calculation
top_plate = cell(accurancy*square_length_upper+1,accurancy*square_length_upper+1);
for run_y = 1:size(top_plate,1)
for run_x = 1:size(top_plate,2)
top_plate{run_y,run_x}.position_x = (-(size(top_plate,2)-((size(top_plate,2)-1)/2))+run_x)/accurancy;
top_plate{run_y,run_x}.position_y = ((size(top_plate,1)-((size(top_plate,2)-1)/2))-run_y)/accurancy;
end
end
top_plate_speed_x = cellfun(@(x) x.position_x,top_plate);
top_plate_speed_y = cellfun(@(x) x.position_y,top_plate);
top_plate_speed = 2*pi*speed_top*sqrt(top_plate_speed_x.^2+top_plate_speed_y.^2);
I hope i described it understandable. Thanks in advance

I cannot run your code, since I do not have all your variables.
If you want to convert your numeric matrix to a cell array, use the num2cell (link) function.

Sorry i forgot one variable. Here is the working code:
%%Calculation Parameters
accurancy = 250; %[Points per m]
rotation_accurancy = 5; %[Degrees per iteration] Must be a multiple of 360
radius_bottom = 0.125; %[m]
speed_bottom = 200; %[U/min]
position_upper_x = 0; %[m]
position_upper_y = 0; %[m]
square_length_upper = 0.06; %[m]
speed_top = 100; %[1/min]
contourf_accuracy = 10; %Number of different fields in the figure
%%Convert Parameters
speed_bottom = speed_bottom/60; %convert from [U/min] to [U/sec]
speed_top = speed_top/60; %convert from [U/min] to [U/sec]
%%Calculation
top_plate = cell(accurancy*square_length_upper+1,accurancy*square_length_upper+1);
for run_y = 1:size(top_plate,1)
for run_x = 1:size(top_plate,2)
top_plate{run_y,run_x}.position_x = (-(size(top_plate,2)-((size(top_plate,2)-1)/2))+run_x)/accurancy;
top_plate{run_y,run_x}.position_y = ((size(top_plate,1)-((size(top_plate,2)-1)/2))-run_y)/accurancy;
end
end
top_plate_speed_x = cellfun(@(x) x.position_x,top_plate);
top_plate_speed_y = cellfun(@(x) x.position_y,top_plate);
top_plate_speed = 2*pi*speed_top*sqrt(top_plate_speed_x.^2+top_plate_speed_y.^2);
I want to integrate the double array top_plate_speed to the cell top_plate. But this without a for loop if this is possible. I tried it as well with the num2cell function but it couldn't solve my problem. Thanks for your help

‘I want to integrate the double array top_plate_speed to the cell top_plate.’
What do you intend by ‘integrate’? If you want to do numerical integration, use the trapz (previously quad) or similar functions.
