I tested whether the arrays were equal by adding the following code just before the failing Assert.

<code>
if (TC_Variables.MDArrays[s].Value.Value.DataType == 10) {
var lhs = TC_Variables.MDArrays[s].Value.Value;
var rhs = PublishHelper.ReceivedDataChanges[t].MonitoredItems[i].Value.Value;
var rawDimensions = TC_Variables.MDArrays[s].Value.Value.FloatMatrix;
var dimensions = rawDimensions.substring(1, rawDimensions.length - 1).split('][').map(function(x) { return parseInt(x); });
var rank = dimensions.length;
if (rank == 2) {
for (var xi = 0; xi < dimensions[0]; xi++) {
var xistr = "[" + xi + "]";
for (var xj = 0; xj < dimensions[1]; xj++) {
var xjstr = "[" + xj + "]";
Assert.Equal(lhs[xistr][xjstr], rhs[xistr][xjstr], "Unexpected value for " + xistr + xjstr);
}
}
}
}
