MATLAB: Structures to matrix for preparing for classification

cell2matdata type conversionstruct2cell

i have a structure , and there are 550 structures in that structure which every structure has 26 matrices

how i can make a matrix which has 550 colums (for 550 structures) and its rows have matrices elements (26 matrices elements )?

thank you ♥

in fact , this structure is a glcm properties matrix and i want prepare

it for classification

Hi Amir Naderi,

if all data to concatenate are within the field 'property' and have same size of matrix you can apply struct2cell and cell2mat:

GLCM_matrix = cell2mat(struct2cell(GLCM_property(1).property));

Kind regards,

Robert

features = [f1; f2]

However, what this will get you is a 2 x 1 struct array, since graycoprops returns a struct. Perhaps you might like

features = cell2mat([struct2cell(f1), struct2cell(f2)]);

but perhaps not. Since you used offsets, there is a possibility that each output has multiple values. You might want to

features = reshape(features,[],2).';

where the 2 is the number of different grayprops that you are putting together.

subs(MyExpression, fieldnames(MyStruct), struct2cell(MyStruct))
