variable being saved as nonsence

Hi,

So in the past, when Ive had to save variables from the workspace in the past I've had no issues. However I am currently trying to save a variable (of a matrix containing numbers) as a .txt and for some reason I'm having a wierd issue.

In the command window I use

cd(...)
save('test.txt','testmatrix','-ascii')

Whichin the past has worked fine for me, however with this matrix it is giving me complete nonsence, and is just outputting a .txt full of stuff like

†㈠㜮〶〰〰ⵥ㐰

I have literally zero ideas as to what is causing this, yet a few may be it is quite a large matrix (50x400), mostly containing double precision variables. A a few cells contain a 0 value. Any of these may cause an issue? If not what could it be?

Cheers.

Did you change of Matlab version ?

I just did it with R2014a

testmatrix = rand(50,400);

save('test.txt','testmatrix','-ascii')

and i got a text file such as

7.9333239e-03   7.2173747e-01   5.0775133e-01   7.7271278e-01   1.4579592e-01   7.6052624e-01   1.7149844e-02   1.2863135e-01   3.1398573e-01   7.4287948e-01   1.9866456e-01   6.9662297e-01   3.8364462e-01   6.5203224e-02   6.7058812e-01   4.6045824e-01   4.0180554e-01   3.5262205e-01   5.6614612e-01   7.7905297e-01   7.5873115e-01   7.7782343e-01   7.5305231e-01   5.0488754e-01   8.4238319e-01   2.8728398e-01   9.5399787e-02   6.4921268e-01   2.4375847e-01   8.7876870e-01   
...

this works just fine .

Nope, always been using R2014a, not had this issue before yet now I do. From the same code/workspace I can save other variables with no issues, yet not this one.

[Orion]

Kinf of weird.

to be sure, did you check the type of your data ?

>> class(testmatrix)

ans =

double

[David]

Yup, getting ans = double when checking class. Has worked with double data in the past/other variables.

[David]

Ah ha, fixed it; sorry for taking you your time mate. Asked IT at where I work and it turns out there was a messup with the software I was using. The code works fine. Sorry/thanks again!

[Orion]

Good,

I was running out of idea :)
