Operator '>=' is not supported for operands of type 'cell'

Hi guys I have a problem in comparing two cells.

My input cells are T{n}, where n=3

• T{1} [mx4]
• T{2} [nx4]
• T {3} [k x 4]

and thor cell [sx1] (Data tipe is a datetime)

To simplify I m looking for all index of T{2} that verify the following in which I am comparing datetimes:

find((T{2}(1:end,1))>= thor(1,1) & (T{2}(1:end,1))< thor(2,1));

The problem is the operator but I guess is "1:end" because the following code worked properly..

find(T{2}{2,1}>= thor{2,1} & T{2}{2,1}< thor{3,1});

It's helpful to upload an example of the data, rather than just describing it, for two reasons:

• it saves us from re-creating data to test any code
• it safeguards against your description containing any inaccuracy compared to what you actually have

In particular, it is not perfectly clear whether the contents of the elements of T are numeric arrays, or cell arrays. We can make a guess, or try both ways, but it's so much easier if we just see the data.

I attach my input data

I got an error message:

Unable to read MAT-file <.../T.mat> File might be corrupt.

For both of them?

S1 = load('thor.mat') % okay

S1 = struct with fields:
    thor: {537×1 cell}

S2 = load('T.mat') % corrupt

Error using load
Unable to read MAT-file /users/mss.system.YD2TnT/T.mat. File might be corrupt.

T = {[], datetime('tomorrow')}

T = 1×2 cell array
    {0×0 double}    {[30-Jun-2021]}

thor = {datetime('today')}

thor = 1×1 cell array
    {[29-Jun-2021]}

T{2} <= thor{1} % false

ans = logical
   0

T{2} <= thor(1) % error

Comparison is not defined between datetime and cell arrays.

The next-to-last line indexes into thor using curly braces to extract the contents of the first cell, the last line indexes into thor using parentheses to extract the first cell.

It does not work either. My T{2} in not a value but an array mx4

edad = x.age;

Unable to resolve the name 'x.age'.

H = x.sex == "female";
M = x.sex == "male";
idx = x.localization;

% Filtrar los datos por sexo y calcular los conteos de edades
femaleCounts = countcats(categorical(edad(H & idx)));
maleCounts = countcats(categorical(edad(M & idx)));

% Obtener las categorías de edad y ordenarlas de forma ascendente
ageCategories = categories(categorical(edad));
ageCategories = sort(ageCategories);

% Crear el gráfico de barras apiladas
figure;
bar([femaleCounts maleCounts], 'stacked');
legend('Mujeres', 'Hombres');
xticks(1:length(ageCategories));
xticklabels(ageCategories);
xlabel('Edad');
ylabel('Cantidad');
title('Análisis de Edades en Hombres y Mujeres con Cáncer');

% Ajustar el tamaño de la figura
fig = gcf;
fig.Position(3:4) = [800 500];

I do not understand how this solves the user's difficulty?
