matlab - Calculating the norm of each row in a matrix -

-

this question has answer here:

i have nx3 matrix (a) columns x,y,z respectively. want calculate norm sqrt(x^2+y^2+z^2) each row. did loop that:

for = 1:length(a) result(i) = norm(a(i,:)) end

is there other way avoiding loop?

thanks

you can this:

sqrt(sum(a.^2, 2))

your method returns 1x3 returns 3x1. if want can transpose doubt need to.

i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
