How to load only one parameter from a .mat file which contains several parameter?

Hi MATLAB users,

I've got a question which really helps me to do my calculations faster.

Suppose we have a data_collection.mat file which contains:

data1 <351x40x160>

data2 <300x39x200>

data3 <400x50x520>

Suppose a .mat file even bigger in which every time I load, it takes tremendous amount of time. But in fact I need only one of parameters (such as data1). Is there any way to load ONLY this and ignore the other? By that the desired data will load much faster.

Thanks so much in advance,

Mehdi

S = load('data_collection.mat', 'data1')

[Walter Roberson]

S = load('data_collection.mat', 'data1')

Yes, that's I mean.

Sorry for little mistake :)

@Mehdi : Or you can alternate

load('data_collection.mat', 'data1') directly

Thanks Chandra and Walter :)
