I have a mat file with certain data. It has 10 rows per 500 columns but when I do:
matriz = load('Planilha.mat');
disp(size(matriz));
The result is 1 by 20. What's totally different than expected.
How do I get the correct size of a .mat file?
In addition to Marcelo Uchimura put in the answer, it is worth remembering that when you use
matrix=load('data.mat')
or
matrix=load('data.mat','variavel')
You have a structure answer, not the matrix saved. Assuming that the flame matrix mt , to access it it is necessary to use
st=load('data.mat')
matrix=st.mt
or just use
load('data.mat')
or
load('data.mat','variavel')
This will put the array in the workspace, the way you want it.
Inspect saved variables within .mat with
whos -file Planilha.mat
Then, to load the variable you need, do
matriz = load('Planilha.mat','nomedavariavel')
