MATLAB: Export to .csv with specific notation

arraydelimitermatrix

Hello,

From matrix A (A = [0 1; 1 2; 2 3] I need to create a .csv file in the following format:

{0.000,1.000}, /new line
{1.000,2.000}, /new line
{2.000,3.000}, /new line

I am managing to import it into an array but I do not know how to specify the formatSpec of the output. Any help would be appreciated.

Many thanks, Ioanna

[fid,msg] = fopen('name.csv','wt');
assert(fid>=3,msg)
fprintf(fid,'{%.3f,%.3f},\n',A.');
fclose(fid);

The file it produces is attached, and looks like this:

{0.000,1.000},
{1.000,2.000},
{2.000,3.000},

Then somefunction.m does not take input arguments for example:

function x = somefunction
x = 2;
end

if you call

x = somefunction()

you get x = 2

you can also just enter

x = somefunction;

You need to change the format string.

I would do something like this:

   m = textscan(fid,'%f%f%f%s%s','HeaderLines',2, 'Delimiter',',');

If you only want to read the first 2 fields and ignore the rest, add ‘*’ to the format string elements you want to ignore:

m = textscan(fid,'%f%f%*f%*s%*s','HeaderLines',2, 'Delimiter',',');

There are other options to read the dates and times. See the documentation section on formatSpec (link) for details.
