Concatenating matrices in a structure with same size into a 3D array.

Hello,

I have a structure consisting of 25 matrices, all of the same sizes, 5750 x 360. I am trying to figure out how I can concatenate this array in the third dimension so that I can get an array of 5750 x 360 x 25.

x_mat.mat1=rand(100, 5);
x_mat.mat2=rand(100, 5);
x_mat.mat3=rand(100, 5);
x_mat.mat4=rand(100, 5);

structfun(@(x) cat(3, x), x_mat, UniformOutput=false)

ans = struct with fields:
    mat1: [100×5 double]
    mat2: [100×5 double]
    mat3: [100×5 double]
    mat4: [100×5 double]

I've tried this, but it returns the same structure.

Thank you in advance. :-)

x_mat.mat1=rand(100, 5);
x_mat.mat2=rand(100, 5);
x_mat.mat3=rand(100, 5);
x_mat.mat4=rand(100, 5);

c=struct2cell(x_mat);
A=cat(3,c{:});
size(A)

ans = 1×3

100 5 4
