Hi all I am trying to convert Latex code to Mathematica by using the example: ToExpression["\\sqrt{x y}", TeXForm]. I came across a problem of "non-math mode": The code I put into Mathematica is as below: ToExpression["\\lbrace 1- \\Phi [({{\\Sigma}_{22} - \ {{\\Sigma}_{12}})*(-{X}_{4}* {\\beta}_{4} - {\\Sigma}_{21}*\\(\\left( \\begin{array}{c} {\\varepsilon}_{1} \\\\ {\\varepsilon}_{2} \\end{array} \\right)\\))]\\rbrace*\\phi({\\varepsilon}_{1} , \ {\\varepsilon}_{2})*(1-\\alpha_{1}\\alpha_{31})", TeXForm] The error info is: Import::texerr: Error: Math primitive \delimiter in non-math mode. How can I solve this problem? Thanks a lot !
