Execluding an array member ( equivelent to [] operator in MATLAB )

[hefty1985]

Hi Guys,

I am new to this web. I have a fairly simple problem. I have an array of certain double precision numbers. What would be the best way for execluding one of the array members without affecting the other values. For example:

Input array: [ 0 1 2 7 6 **0** 4 9 8]

Desired Ouput array is: [ 0 1 2 7 6 4 9 8]

I know in MATLAB it can be done by [] brackets any idea of a good function that would carry out such functionality.

Best regards,

BASHAR

It may be time to upgrade from arrays to STL vectors. If you do so you will gain many things, incuding the method erase which removes a specified element,

I agree with ravenspoint.

However, if you wish to do it the hard way, use a second array as a map:

Input array: [ 0 1 2 7 6 0 4 9 8]
Map array: [ 1 1 1 1 1 0 1 1 1]

Then iterate the map array and only use elements from the input array that are marked in the map.

Then iterate the map array and only use elements from the input array that are marked in the map.

That's a clever solution.

Use a bit array for the the map, so as not to double your storage requirements.

If you enjoy fancy footwork, make the map entirely abstract and use simple compression, so that

[ 1,1,1,0,1,1] becomes [0-2,4-5]
