Re: [Scilab-users] Help with reading data (csvRead)
Hi Samuel
OK, I trust it's just a matter of how the Mread matrix is displayed.

Indeed it looks simpler than using csvRead, I will look into this
function as well. It looks like it cuts off some of the decimals.
Very unlikely. At least not a single one for the full file you sent to me:
f = mgetl(filename);
f(1:5) = [];
s = sprintf("%9.3f %+10.4f %+10.4f \n",Mread);
and(f==s)
-->f = mgetl(filename);
-->f(1:5) = [];
-->s = sprintf("%9.3f %+10.4f %+10.4f \n",Mread);
-->and(f==s)
ans =
T
Trailing zeros are not displayed in the console. This can be
misleading (and is unconvenient), but actual values are ok.

Re: [Scilab-users] Help with reading data (csvRead)
Hi Rafael
So I gather that the separator has to be a single character, when using
csvRead.
Thanks for the tip, I'll use mfscanf instead, it seems to be tolerant ...

Hi Claus,
I do not know how to handle multiple spaces separators in csvRead, but
you can use following code (adapted from recent post by Serge Steer):
// START OF CODE:
u=mopen("example.zma","r");
mgetl(u,5);// reads 5-line header
r=mfscanf(-1,u,"%f %f %f\n");
mclose(u)
// END OF CODE

Rafael

Hi
I'm trying to read a datafile with csvRead, it might be the wrong
function. Please help. The file itself looks like this (only showing
select lines - the file contains 391 lines):
* FILE:C:\Users\claus\example.zma
* INFO: Arb1
* Data: Impedance (ohms), Phase (degrees)
10.000+8.8488 +40.1693
10.199+8.9648 +40.7994

10003.368 +27.2519 +57.4330
2.000 +44.3153 +62.1741
csvRead complains because the column width is changing. I execute:
localdir = "C:\Users\claus\";
filename = _fullfile_(localdir,"example.zma");
Mread = csvRead(filename," ",".","double",[],[],[],5);
This is the error which csvRead gives (line 10 == line 3 in above
shortened dataset):
>Warning: Inconsistency found in the columns. At line 10, found 12 columns
while the previous had 13.
> !--error 999
>csvRead: can not read file C:\Users\claus\example.zma: Error in the
column structure
What is the recommended way to read the ZMA file?
P.S. ZMA = Impedance with 1) Frequency, 2) Magnitude and 3) Phase data.

Re: [Scilab-users] Help with reading data (csvRead)
Hello Claus, Could you please post a true extract of your file, as a file /in attachement/, after that you checked than the issue occurs also with this extract file? It will be easier to test the issue, and it will lead to more reliable tests than copying/pasting a part of your message in a file.
