To pop to three vectors in Matlab by using Java's Stack

Question

I have a function

data1 = conv(data(75:138),hamming(64)); [B,T,F] = tfrwv(data1, 1:length(data1), length(data1));

I cannot push to three the stacks [B,T,F] so it is better to make one stack instead

BTF = java.util.Stack();

and now run

data1 = conv(data(1:64),hamming(64)); BTF.push(tfrwv(data1, 1:length(data1), length(data1)));

and now is the problem of popping the data from BTF into vectors B, T and F. I run unsuccessfully

[B,T,F] = BTF.pop();

The command BTF.pop() returns 127x127 double. So I need to handle the stack by some other function or start from scratch, probably from three stacks.

How can you pop from one stack the data of three variables into three vectors?

Answer 1

The problem of your code is, that BTF.push(tfrwv(...)); pushes the first output argument only. Use [B,T,F]=tfrwv(...);BTF.push({B,T,F}); instead.

Answer 2

Use BTF.push({B,T,F}) instead, to deliver all the arguments
