matlab里删除矩阵一些列的函数

function matrix = deleteMatrixColumn(matrix,index,numRow)

index = sort(index);

lastIndex = 0;

tempMatrix = [];

for i=1:size(index,2)

if index(i)==1

lastIndex = 1;

elseif index(i)==size(matrix,2)

break;

else

tempMatrix = [tempMatrix matrix(1:numRow,lastIndex+1:index(i)-1)];

lastIndex = index(i);

end

end

if lastIndex<size(matrix,2)

tempMatrix = [tempMatrix matrix(1:numRow,lastIndex+1:end)];

end

matrix = tempMatrix;
