multiple if elseif statement
显示 更早的评论
How can solve this (using if and esleif statement)?
if lambda_theta <= 0
F_lambda_theta2 = 1 - ( (-12.986 * lambda_theta) -(123.66 * lambda_theta.^(2)) - (405.689 * lambda_theta.^(3)) ) * exp( -(Tu/1.5)^1.5 ) % lambda_theta2=<0
else
F_lambda_theta2 = 1 + 0.275 * ( 1 - exp( -35.0 * lambda_theta ) ) * exp ( -Tu/0.5 ) % lambda_theta2 > 0
end
% Re_theta2
if Tu <= 1.3
Re_theta2 = ( 1173.51 - 589.428 * Tu + ( 0.2196/(Tu^2) ) ) .* F_lambda_theta2
else
Re_theta2 = 331.50 * ( Tu - 0.5658 ) ^ (-0.671) * F_lambda_theta2
end

Show us your code and ask a specific question.

is lambda_theta a scalar or potentially a vector?

You can refer to the below documentation links of ‘if else statements’ to get you started with implementation. This also has some examples.
In order to get a better understanding of Element operations and array vs matrix operation and get clarity on the difference between them, you can refer to the below documentation links. Based on your use case, you can use either ‘*’ or ‘.*’ .
