Thank you very much for the response. I found a much simpler way to do it though. I just converted the array into a matrix and then published the matrix like this:

Mat matrixarray = Mat(11,20,CV_32FC1,deptharray);

diff.PubDepthArray(matrixarray);

where the method to publish the array looks like this:

void GetDiffImg::PubDepthArray(Mat depthArray){

    cv_bridge::CvImage diffImgMsg;
    diffImgMsg.encoding  = sensor_msgs::image_encodings::TYPE_32FC1;
    diffImgMsg.image    = depthArray;

    depthArrayPub.publish(diffImgMsg.toImageMsg());

Hello,

I'm stuck at my program to publish a 2 dimensional array. The array kinda looks like this:

int deptharray[4][5] = { {0, 0, 0, 0}, {0, average11, average21, average31, average41}, {0, average12, average22, average32, average42}, 0, average13, average23, average33, average43}, }; I also read several posts about how to publish an int32MultiArray but unfortunately none of my attemps to publish this array of known values worked. All examples that I have seen have unknown sizes and then use the push_back function in a for loop. I'd be really glad if you could help me. Thank you very much
