Delete Column from matrix

Hi, I'm tring to delete item from structure, the structure is: A.data A.smpf

When the program arrives in this instructions:

A.data(1,(c_x+1):end)=[]; c_x is 13 and A.data is 1x180000. I have this error: A null assignment can have only one non-colon index.

Some help? Thanks

What are you trying to do? It looks like you are tying to delete a portion of a column. Are you sure you are not trying to set the values to nan or 0 or -inf.

[TAB]

Try

A.data((c_x+1):end)=[];
