MATLAB: Error: Unable to perform assignment because brace indexing is not supported for variables of this type

errorfor loopMATLAB

Hi everybody,

if I launch this code using a single POINT it works, if instead I insert it inside a loop (with POINT that change at every iteration) this message error appears to me:

Unable to perform assignment because brace indexing is not supported for variables of this type

POINT=[x,y,z]
nRow = size(A, 1);
for iRow = 1:nRow
STRAIGHT=-20:.01:20; 
STRGT{iRow}=repmat(POINT,length(STRAIGHT),1)'+((A(iRow,:))-POINT)'*STRAIGHT;
end

How can i resolve it?

Thank's!

STRGT=cell(1,nRow); % before the loop ,also move STRAIGHT outside the loop

MATLAB: Invalid use of operator in for loop

theta0 = tand(v0y/v0x)

while theta0 > 90 || theta0 < 0

% where the '>' gives an error message

end

Changing this to a while loop should fix your issue. A for loop counts for a specified number of iterations, the while loop iterates while some condition is met. So for your case you want this loop to run while theta0 is greater than 90 or less than 0. when that condition is no longer true, then the loop ends. Need to make sure that the code inside the loop changes theta0 or it will loop forever. If your do not plan on changing theta0 inside the loop, then Paul is correct above with using an if statement.

MATLAB: Repeat all operations for n rows inside an array (with n unknown)

M = [0.3  0.4   4; ...
     0.5  0.6   3.1];
nRow = size(M, 1);
for iRow = 1:nRow
    yourOperation(M(iRopw, :)) ...
end

If you want to collect the results, use either a matrix again:

result(iRow, :) = ...

Or if the output has different sizes or classes, use a cell array:

Result = cell(1, nRow);
for iRow = 1:nRow
    Result{iRow} = yourOperation(M(iRopw, :)) ...
end
