Hi !

I am trying to run a file its from J Fessler libray !

When i type nufft ! it runs a .m file which uses some function and it gives following error

Undefined function or method 'isvar' for input arguments
of type 'char'.


its when function is trying to execute these lines




Error in ==> nufft2_err_mm at 32
if ~isvar('alpha') | isempty(alpha)

Error in ==> nufft at 39
printm('err alf1 %g best %g', ...



if ~isvar('alpha') | isempty(alpha)
alpha = [1]; % default Fourier series coefficients of scaling factors
end
if ~isvar('beta') | isempty(beta)
beta = 0.5; % default is Liu version for now
end

isvar() is not provided by Mathworks; it is perhaps provided by a different
portion of the library.

You can write your own isvar() as

isvar = @(name) exist(name, 'var');
