Out of memory

Out of memory

Dear all,

 

I'm using Mathcad 15 M030 for analysing data. I got the "out of memory" error message if I paste the file I have attached in a mathcad table.

I know that the topic has been already discussed in this forum but I didn't find any workaround.

Is there in the meantime a new solution?

Thank-you very much for your support.

 

Regards

Re: Out of memory

Hi,

All data must be on the right. Something is wrong with the central column (B).

Re: Out of memory

Hello,

 

Thank-you for your reply.

It is better now but I still have out of memory error message if the table is bigger (73000 x 3).

Is there any way to work with "big" data without this problem?

Re: Out of memory

Please provide your Mathcad worksheet in archive.

Re: Out of memory

One method would be to read in the data using one of Mathcads READ.... functions.

But as you are using real Mathcad and not crappy Prime,  you can copy the data from your text file (Ctrl-C), go to Menu - Insert - Data - Table, highlight the first three columns in the first row of the data table which was just created and insert the copied data (Ctrl-V).

It should work without highlighting the top three cells but it doesn't for me.

I attach a worksheet with the inserted data.

Thats not really "big" data for Mathcad and sure should work OK. You may consider not to copy the data but rather read it in from your text file in case the data changes now and there.

@Francesco:

No, nothing wrong with the data. Its just your European installation of Excel which expects a comma as decimal separator rather than the decimal point provided in the text file. So the data 0.17 is interpreted as text by your Excel and not as a number and so it not right-, but left-justified.

 

Re: Out of memory

In case you are unsure as to how to read in the data - with the data format you provided you can simply use READPRN to do so:

Dear Werner,

 

It works, thanks a lot.

Mathcad is still consuming much memory 1.5Gb but I get no error message anymore.

Can't imagine why Mathcad should take up that much memory for a matrix that small !?? Hard to believe!

Re: Out of memory

Thanks Werner, I hadn't noticed it.

Re: Out of memory

Do you have any chance to update your MC15 M030 version?
