Delete/remove entire rows and columns containing an element that satisfies a condition (e.g. when the element is an imaginary number)

In an array containing elements that are imaginary numbers, how can I remove the entire row(s) and column(s) containing any of these numbers?

You should be able to loop through the columns or rows of the array and check them with isreal:

Answer 1

[Jonas]

where=yourMatrix==yourCondition;
yourMatrix(any(where,2),:)=[];
yourMatrix(:,any(where,1))=[];

or

[row,col]=find(where);
yourMatrix(row,:)=[];
yourMatrix(:,col)=[];

if your condition being a complex number you can use where=~isreal(yourMatrix)

Answer 2

[Walter Roberson]

valgood = imag(YourMatrix)==0;
rowmask = all(valgood,2);
colmask = all(valgood,1);
newMatrix = YourMatrix(rowmask, colmask);
