Write a file starting in column 7.

1 view (last 30 days)
Dear, I have a question about write the data in the file.
Is possible write a data in the file starting in column 7 ?
For example:
My program is writing:
Line 1 and Column 1 until 36
Line 2 and Column 1 until 36
.
.
Line 19 and colund 1 until 36.
I would like write starting in column 7 until 42.
that is:
line 1 and Column 7 until 42
line 2 and Column 7 until 42
.
.
line 19 and Column 7 until 42.
That is, all line of column 1 until column 6 stay empty.
Is it possible ?
thank you

Certainly possible but specifics depend on what kind of file you're trying to create???

If your data is in csv format, you can use the command csvwrite with row and col parameters as follows:
row = 0;
col = 6; % row and cols are zero-based so row=0 and col=0 are the first row and column, respectively.
csvwrite(filename, yourdata, row, col);

Thank you for answer.
I would like write the file in .mat
I am saving the file this form: save('test_Cj3p09_30082020_4points', 'C', '-append')
The variable that I want to save is C, where C is the 19x36 double.
Starting in columns 1 until 36.
But I need save this variable starting in column 7 until 42.
Thanks in advance

Try appending zeros to C in the columns from 1 to 6, like this:
C = [zeros(19,6) C];
