Converting .dat to .mat?

I have cube.dat file with dimensions 59X44X76. i am trying to convert it into .mat file with same dimensions. I tried following code, once i run the code it never stops

Option1:

data=textread('cube.dat'); save data.mat;

Option 2

data=textread('cube.dat'); save data.mat data;

Those both codes are running forever. Is there somehting am i missing (like format or anything)?

Which part is hanging: the textread(), or the save()?

[Rhai]

 textread('cube.dat')

[Rhai]

here is the code which creates "Cube.dat" is 128x128x8

clear all;close all; xl=58 yl=44 zl=76

fid=fopen('cube.dat','w')

for k=1:zl

    for j= 1:yl

        for i= 1:xl

            %fprintf(fid,'%d %d %d %f %f\n',i,j,k,1);

            cube(i,j,k)=1;

        end

    end

end

And i need to create cube with 58x44x76.that's where i used above code

data=textread('cube.dat'); save data.mat data;

And its getting hang in "data=textread('cube.dat'); "

Thanks

Where did you upload cube.dat? http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

Your code is not writing anything to cube.dat .
