How can I read or load a .txt with multiple vector/matrix in it?

Hello,

I am a beginner in Matlab, so if my question is very obvious please excuse me.

I want to read a .txt file with multiple vectors and matrices in it. These vectors/matrices are also from a different size. The size of these vectors/matrices is known in front.

I already tried the function load and textread, but is gives an error.

For example, the txt file: With first matrix is 1x1 second matrix is 2x10 third matrix is 10x1 etc.

Thanks for your help!

Use the function dlmread by changing its parameters to access the txt file at different line and column offsets. For the text file example you posted:

M1 = dlmread('file.txt',' ',[0 0 0 0]); %the 1x1 matrix
M2 = dlmread('file.txt',' ',[1 0 10 1]); %the 10x2 matrix
M3 = dlmread('file.txt',' ',[11 0 11 9]); %the 1x10 vector
