MATLAB: Am I unable to use “conAssign” function

MATLAB

In previous versions of MATLAB I used the "conAssign" function to set optimization structures and then used Knitro for optimization. However I can not find "conAssign" in Matlab R2019a. Did you remove or change it?

The "conAssign" function is not actually a built-in MATLAB function. It is a third-party function created by TOMLAB Optimization.

MATLAB: How to plot a cell referenced map

You can create a "cell referenced" plot by first creating a "GeographicCellsReference" object using the function "georefcells". The code below illustrates this workflow using a built-in MATLAB example:

>>load topo
>>R = georefcells(topolatlim, topolonlim, size(topo));
>>worldmap world
>>setm(gca,'mapprojection','pcarree');
>>S = geoshow(topo, R, 'DisplayType','texturemap');

Note that here, "topolatlim" and "topolonlim" specify the limits of the latitude and the longitude in increasing order (i.e. from South to North and West to East, respectively).

For releases R2015a and earlier, the function "georefcells" is not available. In earlier releases, replace the line of code that calls "georefcells" with

>>R = georasterref('LatLim',topolatlim,'LonLim',topolonlim,'RasterSize',size(topo));

Also note that the built-in example is slightly different in earlier releases, so it is necessary to construct "topolatlim" and "topolonlim" from the data in the MAT file.

MATLAB: Does using ‘copyobj’ function with ‘uitreenode’ break node selection

This is a known bug which has been resolved in MATLAB R2018b.

If you are experiencing this issue in MATLAB R2018a or an earlier release, you can use one of the following workarounds:

1. The recommended workaround is to create a custom function to copy 'uitreenodes' as shown below:

function nodeCopy = treeNodeCopyObj(node, parent)
       nodeProperties = get(node);
       nodeProperties = rmfield(nodeProperties, 'BeingDeleted');
       nodeProperties = rmfield(nodeProperties, 'Type');
       nodeCopy = uitreenode(parent, nodeProperties);
  end

2. Another potential workaround, which is less recommended, is to create a custom 'copyobj' function and put it in your path above the built-in version as shown below:

function nodeCopy = copyobj(node, parent)
if isa(node, 'matlab.ui.container.TreeNode')
    nodeProperties = get(node);
    nodeProperties = rmfield(nodeProperties, 'BeingDeleted');
    nodeProperties = rmfield(nodeProperties, 'Type');
      nodeCopy = uitreenode(parent, nodeProperties);
else 
    builtin('copyobj', node, parent)
end
