Hello!

I'm trying to create a 4x5 matrix containing a 1x3 structure in each of its cells but I can't get the result shown in the picture. I only managed to get a 9x1 structure.

position = {'corner';'edge';'corner';'edge';'inside';'edge';'corner';'edge';'corner'};
temperature = {25;25;25;25;50;25;25;25;25};
ic = {0;0;0;0;0;0;0;0;0};
PCB = [position, temperature ,ic]
cell2struct(PCB,{'position';'temperature';'ic'},1)

Does anyone know how to create it? Thank you very much!

"What would be the correct way to carry out the structure of 4x5?"

That depends on the format of the input data:

Are they generated one-at-a-time in a loop (or similar), or are they available in arrays?
Can the data arrays (if in arrays) change size? What size do the arrays use?

Possibly struct or one of the conversion functions would suit your task.

The data are available in fixed-size arrays as follows:

- position: (4x5)

- temperature: (4x5)

- ic: (4x5)

If the field values you pass into the struct function are a cell array, MATLAB will make a struct array the same size as the cell array. Each element of the struct will contain the data from the corresponding cell of the cell array.

A = {1 2 3; 4 5 6};
B = {'apple', 'banana', 'banana'; 'cherry', 'cherry', 'apple'};
S = struct('number', A, 'fruit', B);
T = S(2, 2) % T.number is 5, T.fruit is 'cherry'
